In the coil processing, due to the deviation of the coil itself or the machine, once the edge of the coil is not aligned, it will cause errors in subsequent processes, resulting in material waste or machine adjustment. In order to reduce the occurrence of such situations, the web guiding system can provide a solution for the edge position control of the coil.

Web control refers to the technical operation that the coils must always be kept neat and consistent during the spraying, printing, punching, laminating, slitting, or other coil winding processes. When processing coils, it is necessary to perform edge guiding timely on the offset coils. This process is called web guiding. The equipment of the whole process constitutes a system. The web guiding system includes a controller, a web guide sensor, an electric drive, and a web guide mechanism.

The web guiding system is a closed-loop controller, which includes the controller, sensor, and web guide mechanism, as the basic complements of the system. First, the sensor detects the edge or of the coil, and the system automatically reads the offset of the actual position and the setting of the coil. Convert the offset into an electrical signal and send it to the controller. After the signal is amplified and calibrated by the controller, it is output to the driver. The linear driver drives the deviation correction mechanism according to the magnitude of the signal, to restore the coil to the set position. The drive signal of the current driver is only proportional to the deviation of the coil, which makes the web guiding system possible to provide precise control for various coils.

When the rolling speed of the material is relatively low, the speed of the motor should be low speed, otherwise, it will easily lead to over-correction. When the rolling speed is relatively high, then the speed of the motor should also be a high-speed correction. Adjust the winding speed of the correction motor through the frequency adjustment. The automatic web guiding can also be operated manually. It has the functions of automatic detection, automatic tracking, automatic correction, etc, which can track and correct the edges of paper, non-woven fabrics, film, aluminum foil, strip steel and other materials to ensure the roll winding and slitting neatly.

The web guiding system has a compact structure, good mechanical rigidity, low inertia, suitable for high-speed and high-precision edge position guiding in the middle of coil processing.

The anchor is widely used for dredging, offshore mooring, fish farm, and yachting operation, with SS316L material option or with H.D.G. finishing for your multi-purposes. You sometimes need to set two anchors in a crowded anchorage, with anchors at the bow and stern of the marine to limit its ability to swing. Two anchors set from the bow at a 60° angle are another good way to improve security against swinging and dragging, and they allow you to shorten the rodes and use less scope. In heavy weather conditions, where one anchor may not have enough holding power, setting a second anchor may be critical to staying put. Remember that as the wind speed doubles the force on the marine (and the ground tackle system) increases by four times.

Choose an anchor that’s the right size for your marine and the locations and weather where you anchor. Take the anchor manufacturer’s suggested sizes into account and consider your marineing style. Do you typically anchor for two hours or for two weeks, in a lake or in the Atlantic Ocean? The recommended anchor sizes from YSmarines will work well for most marineers, under most conditions.

Sizing an anchor for your marine reinforces, with some limits, the “bigger is better” idea. If your engine fails and you are drifting toward a lee shore, having a properly sized anchor ready could save your marine. But raising the anchor by hand, with no electric powered windlass, calls for light and efficient ground tackle (and a strong back).

You have three options: galvanized steel, Grade 316 stainless steel or lightweight aluminum/magnesium. Most marineers choose a galvanized anchor for cost reasons, with the added advantage of having the highest tensile strength. Stainless anchors resemble works of sculpture to dress up the bow of your vessel.

YSmarines is a professional marine anchor supplier and carries superior quality products with fast delivery anywhere in the world, various types including stockless anchor, folding anchor, spek anchor, bruce claw anchor, etc, with professional certification like DNV-GL, BV, ABS, LRS, RINA, IRS, etc.

How to test the web guide system

After the web guide system has been installed on the machine:

1. let the machine run first, if there is a deviation, adjust the upper layer of fabric firstly. For example, if it is to the left, it needs to be adjusted to the right. In the same way, if it turns to the right, you must adjust to the left.

2. Before turning on the web guiding machine, make sure that the fabric is aligned.

3. Then turn on the web guide equipment. After identifying the fabric, the probe is aligned with the red dot and the upper line is aligned with the edge. Then tighten the lower screw and the position will be located.

4.After locating the position, press the button of “automatic” mode. If there is an offset, it will all be aligned with the upper line.

5. Each layer is the same, and this layer should also be aligned with the red dot. The lower screw must be loosened firstly, and then the probe can be moved and aligned with the red dot.

6. After aligning the red dot and twist the black screw.

7. Then touch the “automatic” mode. If there is a deviation, the machine will swing and automatically correct it.

8. All the systems keep the “automatic” mode. Now the web guide runs automatically, and the machine will not run off when it starts.

An anchor is a vital part of the boat and is one of the most widely used items in the marine industry.”. The anchor is used to protect your boat. It is synonymous with durability and resistance to bursting. The type of bottom—mud, grass, sand or rock—will dictate different choices of anchors, as will the size and windage of the marine, the wind conditions and the sea state When choosing an anchor for your boat, it is paramount to consider both your length of the boat, the weight of boat and weather conditions in your area.

Which style or category of anchor?

Choose between the two most common anchor styles, the fluke and the plow, or if you are marineing in a small marine, on protected inland waters, the inland type.

The most popular type of anchor is the fluke anchor, also called the Lightweight or Danforth anchor, which includes the West Marine Traditional and Performance2 anchors and is often the only anchor on many smaller marines. Light and easy to weigh, it stows flat and holds well in mud or sand. Its excellent holding power-to-weight ratio means you can use a lighter anchor compared to other types, but it doesn’t hold well in grassy or rocky surfaces. Its flukes and stock (the wide crossbar at the top) are more prone to foul on rocks or the anchor rode.

Plow and Scoop anchors—the “single point” style represented by the Manson Supreme, Rocna, CQR, Delta and Claw—have the best all-around holding ability in varying bottom conditions. They generally reset themselves easily if the wind or current changes direction. The newest “scoop” designs, like the Manson and Rocna anchors, include round “roll bars” that self-right the anchor, automatically turning it right side up.

Plow/scoop anchors hold more effectively in grass, mud and sand. They do not have projecting flukes that foul easily, but their shape makes stowing them more awkward (a bow-roller or bowsprit is the best solution). Heavier powermarines and cruising sailmarines often use plows as primary anchors.

For the greatest anchoring security, you should carry two anchors of different styles, one each of the Danforth style and the plow/scoop variety. The type of bottom—mud, grass, sand or rock—will dictate different choices of anchors, as will the size and windage of the marine, the wind conditions and the sea state. Some anchoring situations also call for more than one anchor to be used simultaneously.

YSmarines is one of the leading marine anchor suppliers with high performance, beautiful design with various colors and maximum protection for boats, which can provide the anchor in a wide variety of types to meet customer’s requirements.

3. Touch the “back to center” button, and then touch the “manual” button, respectively pressing the material of the same layer into the material according to the “material penetration diagram”. Run the main machine for a few minutes to move the material for a period of time.

4. In the “manual” mode, adjust the sensor’s position and the moving bracket in a large range and then adjust the rotary knob in a small range. (Adjust the position to the sensor offset display about 50%)

5. In the “automatic” mode, adjust the edges of the other layers of materials to coincide with the edges of the reference based on one layer, and the correction and debugging are completed.

Infrared sensor calibration

For some materials that are not easy to identify, the infrared sensor is required to achieve the best web guide effect.

Steps

1. Long press the “SET” button to make the sensor light flash (release the button after flashing)

2. Tighten the material and put it into the position of the sensor near the light lens (the material will completely cover the circular light-transmitting sheet). Then wait for 3 seconds and remove all the materials from the sensor.

3.Press the “SET” button until the light does not flash, and then release the button. The process of the calibration has been completed.

Common problems in the operation of the web guide system

1. The machine will swing to the limit alarm when it is switched to the “automatic” mode. (Confirm whether the correction polarity is correct and whether the sensor has a signal)

2. The speeds of the left and right swing are inconsistent in the “automatic” mode. (Check if the infrared sensor changes range from 0-100%)

3. When there are different materials in the “automatic” mode and the integrated machine does not swing, the infrared sensor is needed to calibrate the material.
