Title:
SEPARATION DEVICE FOR SEPARATING PORTIONS OF A MATERIAL WEB, LAMINATING MACHINE COMPRISING A SEPARATION DEVICE AND METHOD FOR SEPARATING AT LEAST ONE PORTION OF A MATERIAL WEB
Document Type and Number:
WIPO Patent Application WO/2017/076948
Kind Code:
A3
Abstract:
The invention relates to a separation device (400) for separating portions (04) of a material web (02), the separation device (400) having at least one front clamping device (406), with at least one front clamping point (401), and at least one rear clamping device (404), with at least one rear clamping point (402), and at least one first stretching element (403). The separation device (400) can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching element (403) between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point (401) and the at least one rear clamping point (402), said connection lying completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device (400) on the respective same side as a transport path provided for the material web (02) and/or the portions (04), wherein the transport line in the at least one separation mode is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction (A) and a first transport line lying on the first reference plane and a second transport line lying on the second reference plane have different lengths when the first stretching element (403) is located in the at least one first separation position.
