ABSTRACT:
An apparatus for cutting soft sheetlike material, such as a fabric material, which is subject to elongation due to effect of tensile force. The apparatus has a driving device for supplying a layered severable material in an intermittent step-like manner from an upper position to a lower position. A cutting device cooperates with the layered severable material, when in a stationary vertically-suspended condition, for forming cutting lines of basic configuration therein along the elongate direction thereof, with such cutting lines being repeatedly formed following each advancing step of the material to create cutting lines which extend substantially continuously along the severable material. Devices are also provided for removing unwanted portions of the severable material so as to leave only an essential portion. The severable material includes superimposed sheets of flexible soft material and thin flexible backing, which sheets are separated and independently wound following the cutting step.
