Abstract
An apparatus for cutting a cellular plastic web emerging from a web forming machine into a plurality of predetermined lengths is described. A cutting device including a plurality of mutually spaced filaments is provided on a movable carriage slidably supported on a support stand. The filaments extend transversely of the carriage and the direction of the web emerging from the forming machine. The carriage is mounted on the stand for reciprocating sliding movement. In one direction of traverse, the carriage moves in synchronism and in the same direction as the web and simultaneously divides the web into separate lengths by means of transverse cutting devices. The filaments move alternately toward and away from the carriage to cut the web during successive synchronized movements of the carriage and web. Further, the filaments may be horizontally moved to cut profiles other than straight, vertical sections in the separate lengths of the web.
