ABSTRACT:
A process for continuous cutting of a pile fabric web, having at least one comparatively narrow loopless or napless zone running lengthwise thereon between napped or looped surfaces, lengthwise in the exact center of one of the loopless or napless zones. The fabric web is fed lengthwise along a transport path to the motorized cutting device. The position of the cutting device transverse to the feed direction of the fabric is adjusted automatically so that the loopless and napless zone is cut lengthwise along its exact center by coupling the device with a sensor shoe or slider which senses, e.g. by direct contact, the edges of the pile adjoining this zone.
