Pre-Crimped Wire Cloth Weave Styles

Pre-Crimped wire cloth has extremely accurate openings and is woven much tighter than plain weave. It is typically preferred for vibrating screens and many other applications where sizing is critical.

The wire is crimped prior to weaving by one of two methods;

Punch Crimping

Tooling for this type of set up is far less expensive than wheel crimping although the production rate is considerably slower than wheel crimping.

This method involves a Punch Press fitted with single station tooling (one punch, one die) that produces the desired indentation at or near the bottom of the press stroke.

Punch crimped wire is limited to the accuracy of the feed mechanism that feeds the wire into the tooling after the ram (punch) starts upward and the punch has cleared the die sufficiently to allow the crimped section to travel out of the forming (punch and die) area. With the advent of modern servo-drive feeders, the accuracy is percise, typically within +/- 0.0005" between centers.

Large wire diameters are usually punch crimped due to the high tonnage requirements required to form the high tensile strength, large cross section areas of High Carbon Steel and Oil Tempered Steel abrasion resistant wire which is utilized in Sand and Gravel Screens.

Wheel Crimping

Wire diameters of 3/8" and below are typically processed on Wheel Crimpers due to the much faster throughput speed and reliable accuracy of crimping wheels which are manufactured according to extremely close working tolerances.

		Double Weave Also referred to as "Over and Under" this weave is commonly used for screening operations in smaller openings. Used for medium to heavy wire in relation to screen opening size.

		Scalping Weave This weave is also referred to as "Lock-Crimp" due to the deep crimps which lock the wires in place. For light to medium wire in relation to screen opening size.

		Double Lock Crimp Single shoot oblong openings solve minor blinding problems for better flow.

		Flat-Top Improves material flow with a much smoother, flatter surface than other weaves. Lock weave provides a longer wear life and maintains accurate openings.

		Triple Shoot Long openings will keep sticky or wet material flowing freely. Weave holds wires securely yet permits slight vibration to keep openings clear.

		Intermediate Crimp When open area is important. Extra crimps between the intersections provide a more rigid weave and provide locking and tightness for light wires in relation to the large openings.
