APPARATUS AND METHOD FOR SLITTING A WEB MATERIAL INTO PARTIAL WEBS AND SPREADING THE PARTIAL WEBS

摘要

The invention relates to a device for cutting a web material (10) into several part webs by longitudinal cutting and spreading of the part webs comprising a dispensing device (2) for providing the web material, at least one cutting device (3) designed to produce at least one longitudinal section in the web material and at least one spreading device (4), by means of which the partial webs (10, 10b, 10c) obtained after the at least one longitudinal section are deflected at least partially transversely to their conveying direction (FR) and spaced apart by the deflection, a first control loop (20) being provided by means of in that the position of the web material (10) is controlled transversely to its conveying direction (FR) before being fed to the cutting device (3) and wherein at least a second control loop (30) cooperating with the spreading device (3) is provided by means of which a control of the Deflection of at least one partial web (10a, 10b, 10c) transversely to its fjord (FR).
