ABSTRACT:
The present invention is concerned with a novel and improved cutting mechanism for slicing a flexible sheet that is being advanced endwise continuously to the cutting position. It is particularly advantageous in the slicing of textile materials that are formed continuously as in a carpet making machine, such as those produced by a non-woven bonding procedure described in U.S. Pat. No. 3,657,052.
The present invention comprises an endless belt stretched about two sprockets. The cutting elements are secured to the belt at intervals therealong. Supporting guide means are positioned beneath the upper course or stretch of the belt to assure that the cutting edges of the cutting elements carried thereby follow a path lying in the plane of cutting extending transversely of the width of the sheet being sliced. Means is provided to drive the belt alternately in both directions so that these knives can be reciprocated in the plane of cutting. Means is also provided for adjusting the stroke of reciprocation and in a preferred embodiment, the return stroke is somewhat greater than the forward stroke or vice versa so that there is periodic complete cycling of such a belt and all of the knives are used efficiently.
