Web (manufacturing) in the context of Die cutting (web)

Snips, also known as shears, are metalworking hand tools used to cut sheet metal and other tough webs. Workers use various types of snips, with the cutting edges being straight or curved to various degrees. The style of edge employed will depend if a straight sheer or some type of shape cut is necessary. There are two broad categories: tinner's snips, which are similar to common scissors, and compound-action snips, which use a compound leverage handle system to increase the mechanical advantage.

An intermittent mechanism or intermittent movement is a device or movement which regularly advances an object, web, or plastic film and then holds it in place. This process is commonly used in industry and manufacturing.

This motion is critical to the use of film in a movie camera or movie projector, allowing for a series of still images to be recorded or projected one after the other. When combined with a shutter mechanism, the still images appear as an uninterrupted moving image, due to a phenomenon called persistence of vision.

A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. Release agents are one of many additives used in the production of plastics.

Release agents provide a barrier between a molding surface and the substrate, facilitating separation of the cured part from the mold. Without such a barrier, the substrate would become fused to the mold surface, resulting in difficult clean-up and dramatic loss in production efficiency. Even when a release agent is used, factors such as irregular applications or improper release agent choice may have a dramatic effect on the quality and consistency of the finished product. Many kinds of release agents are used. They are waxes, fatty ester, silicones, and metallic soaps.
