Alpha Marathon Film Extrusion Technologies Inc., Woodbridge, Ont. has developed and delivered  a specialty dimple sheet line that allows the processor to make three different types of product from a single line.

The 3000-mm wide line is powered by multiple extruders and operates at outputs of  2200 lb/hr extruded product. The dimple-forming cylinders move on tracks. Changing from one to another reportedly takes fewer than  2 hr.

The line is also furnished with a fully automatic winder and in-line slitters. Rolls are cut to length, stretch wrapped, labeled and ejected on to a take away conveyor.
