Web guide control refers to the technical operation for the coil materials and must always keep the edge of the coils neat and consistent during the spraying, printing, punching, laminating, slitting, or other coil winding processes. Once the edges of the coils are not aligned, it will cause errors in subsequent steps, resulting in material waste. Therefore, when processing coils, it is necessary to do the correct deviations in time for the offset coils. The whole process is called web guiding. The equipment, which is used for the whole process, constitutes a set of web guide system. A typical system includes a controller, a sensor, a guide mechanism and a driver.
The importance of the web guiding system
The flexo printing machine often adopts an automatic web guide system to ensure the stable horizontal position of the printing material before entering the printing unit. It can detect the deviation of a certain horizontal edge position of the printing material and correct it in time, with an accuracy of ±0.5 mm. Generally, for opaque materials, such as paper and aluminum foil, photoelectric sensors are often used, for transparent materials, such as films, ultrasonic sensors are used. Once the printing material enters the printing area and die-cutting rewinding area, the stability of its horizontal edge position is guaranteed by the installation accuracy of the own processing machine and the parallelism between the rollers
The working principle of the web guiding system
The web guide control system is a closed-loop controller. First, the sensor detects the edge or line of the coil, and the system automatically reads the deviation of the actual position and setting the position of the coil and converts the offset into an electrical signal. They send the signal to the controller. After that the signal is calibrated by the controller, it is outputted to the linear driver. The linear driver drives the deviation correction according to the magnitude of the signal. Then the guide mechanism adjusts the coil to the set position. The drive signal of the current drive is only proportional to the deviation of the coil, which makes it possible to provide precise control for various coils.
Applications of the web guiding system
The web guide system covers a wide range of applications and is essential in various industries such as packaging, printing, labels, building materials, paper pulp, non-woven fabrics, and corrugated paper processing.

A marine searchlight is one of the handiest marine accessories to have aboard. It can help you find a navigation aid or landmark in the dark. A searchlight can also help you find things dropped in the water — if the thing floats, or the water is shallow and clear. It can also be a safety aid, used to signal for help or warn other boats of a hazard in the water. Here’s what to look for in a marine searchlight, whether for your existing boat or as an ­option aboard a boat you are buying.

Installing a searchlight in a Boat

The particulars of the installation have a large impact on a permanently installed searchlight. For instance, a light mounted on a hardtop is convenient to install and may even allow the use of a light that can be aimed manually. However, a light beam shooting over the white bow of a boat often creates a bloom of hazy light that impedes the skipper’s ability to see. If you are set on a top-mounted light, temporarily wire the light and have a helper hold it on your top while the boat is stationary at night so you can check whether this will be a problem for you. Mounting the light forward is preferable. Just be careful about searchlight rail mounts.

Many boat rails vibrate while the boat is underway. This vibration might not seem excessive for a rail, and mostly, it isn’t. But we have observed numerous boats aboard which a small vibration in the rail resulted in a huge vibration to the light’s beam, making it difficult to aim and keep on a target. For this reason, we suggest you favor a light mounted directly to the deck.

Hand-Held searchlights for Boats

Some hand-held searchlights are wired. These connect to a cigarette-lighter receptacle. If you choose this type, consider buying a quality receptacle that locks the male plug from the light. You’ll have to cut off the plug that came with the light and splice in the new locking plug, a simple DIY task. A locking plug and receptacle prevents the light’s cord from pulling out inadvertently in use — a thing that can happen at the worst moment. Also, consider installing auxiliary receptacles at other places from which you might use the light. These include at the bow, on the flying bridge, and in the engine compartment.

Other hand-held searchlights are battery-operated. These provide the freedom to move around the boat without the restrictions of a cord. Of course, unlike wired lights, which have power as long as your boat’s batteries are charged or the engine is running, a hand-held light’s batteries tend to go dead at exactly the same time a wired light’s cord tends to get pulled out of its nonlocking receptacle. Charging vigilance is required for the boater who owns a battery-operated searchlight.

With either type, make sure you select a hand-held searchlight that is heavily armored with rubber or plastic because, as sure as the tide, you will drop it. I also like lights with a brow or rim that extends beyond the lens. This not only adds shock protection but also cuts down glare and helps preserve night vision. Pick the best searchlight for your boat. A marine boat searchlight is vital for boating at night.

Coil materials refer to long-sized continuous materials such as paper, film, sheet, non-woven fabric, metal foil, silk, thread, etc. In the process of uncoiling, technological processing, winding, etc, deviation of the coil materials may occur, due to the deviation of the coil itself or the processing machine. The web guiding control system provides a solution to reduce the occurrence of such situations. The system always tracks the position of the coil material during the production and makes corrections in real-time. It can ensure and improve the quality and efficiency of production.

Working principle of web guiding

The web guiding is to guide the sensor to emit infrared or ultrasonic to monitor the operation of the coil material and send a signal to the controller. After that the controller finds that the web has a positional deviation, according to the preset command by the controller, the controller controls the drive system to swing to correct the web position.

The web guide system uses brushless DC servo motor drive, precision ball screw driv with, compact structure, good mechanical rigidity, low inertia, suitable for high-speed and high-precision web guiding.

The system is composed of a controller, a sensor, an electric driver, and a correction guide mechanism. The sensor detects the edge position of the coil material and reads the deviation between the actual position and the set position, converting the deviation into a voltage signal proportional to it. Then sends this signal to the controller. After the signal is amplified and calibrated by the controller, the signal is output to the electric driver, and the electric driver drives the guide mechanism to perform correction actions according to the magnitude of the input signal to guide the coil material to the preset position.

The primary function of marine navigation lights is to aid prevention of any major accident from happening. All boats – whether big or small are required to have night lights as a part of the navigation systems. This system was introduced in the year 1838 by the United States and then was followed by the United Kingdom in 1849. In the year 1889, the International Maritime Conference was established by the United States to establish proper guidelines to prevent marine accidents. In the year 1897, these rules were officially adopted internationally. The colour of the lights that were required to be used as specified by a set of rules passed in the UK. On the basis of this rule, three colors were chosen: red, green and white. Even today, the marine navigation lighting consists of these three colors.

There is a pattern in which these lights are set up on the ships and boats in conjunction with the International Association of Lighthouse Authorities (IALA) Buoyage Systems. The pattern can be explained below:

There is a light at the right-hand side of the boat (right side when facing the bow of the vessel known as the starboard side) which is green in colour.
There is a light at the left-hand side of the boat (left side when facing the bow of the vessel is known as the port side) which is red in colour.

The importance of lights have been stressed upon enough, but to understand its practical application, imagine a head-on situation (two vessels on reciprocal course); as per COLREGS Rule 14, upon viewing the mandated lights for the situation, each vessel is instructed to alter their course to starboard so as to pass on each other’s port sides. For the purposes of the application of light signals, it is also be important to understand the concept of ‘Aspect’ which, in easy terms, is our own light as viewed by another vessel.

The subject of lights is a rather precise one and being thorough with it requires targeted study. Needless to say, safe navigation is entirely entwined with the knowledge and appropriate application of marine navigation lights.
