348:. The tag stores the information about the items that have been tagged. These converters therefore sometimes incorporate volume electronics manufacturing practices including controlling static electricity, electronic manufacturing test and similar processes. Solving some of the issues of inclusion of materials sensitive to external influences has led to more tech companies embracing roll-based manufacturing processes, with particular success in the lithium ion and solar cell manufacturing sectors.
271:. The system’s controls must put the output signals from the sensors in to a form that can drive the actuator. Many controls today are electronic, typically using an amplifier to convert signals from the sensor, then commanding a special servo motor incorporating a lead or ball screw for guiding actuation. The latest web guiding systems have touch screen controls to simplify the setup procedure. Some web guiding systems have been designed specifically for the converting industry.

163:— threads them through processing machines (such as printing presses, laminating, coating and slitting machines) and converts or changes the web of material into an intermediate form or final product. For example, a converter’s equipment might take a web of plastic film, cut it into lengths, and fuse their edges, thus converting it into plastic bags. This activity is known as web processing.
159:, foil and cloth often are produced in long, continuous sheets that are rolled up for more convenient handling and transportation. These rolls of material vary significantly in size and weight — ranging from 2–203 inches (5–516 cm) wide and weighing as much as several tons. The converting industry takes these continuous rolls of thin, flat materials — known as
242:
When converting from rolls of material, web alignment is an important part of a converting operation as a moving web of material has a tendency to track off course and wander out of alignment during the converting processes. To avoid these problems, engineers have developed a variety of automatic

The process of processing pre-cut cartons or "blanks" and folding them into the appropriate shape to become finished packaging containers is known as tray forming or carton erecting. This is a specific example of a type of converting. These machines can create, for example, nacho trays, chinese

uses a sensor to monitor the web position for lateral tracking, and each has an actuator to shift the running web mechanically back on course whenever the sensor detects movement away from the set path. Actuators may be pneumatic or hydraulic cylinders, or some kind of electromechanical device.

Paper converting can refer to manufacturing processes involving paper as the raw material. This raw material, similar to other converting industries, can be in a roll or sheet form. Paper converting is required for the manufacture of nearly all paper based products, such as magazines, books,

web-guiding systems that assure production accuracy and reduce waste. Web-guiding systems typically are positioned just before a critical stage on a converting machine (for example, just before a print station on a printing press).

Many converting companies will process large diameter, wide rolls of material as this increases the converting efficiency by minimising changes. On completion of the converting process the rolls may be cut into smaller rolls on a
