A sheet material (1) consisting of an mixture consisting essentially of: a) 10-50 percent by weight of random-oriented fibres, and; b) 90-50 percent by weight of a thermoplastic or thermoplastic elastomer; the weight percentages being based on the overall homogeneous mixture; and the sheet material having at room temperature a Shore D hardness of 40 to 85, preferably of 40 to 60, more preferably of 45 to 55. The sheet material (1) is used as a support in punching applications or as the top layer in punching belts (2).

The present invention relates to a book binding device to perform a binding process comprising a coupling process in which two stacks of sheets, such as sheets or, paper, each with at least one sheet, are coupled to each other by tabs in the sheets, and a cutting process to produce the tabs along a respective tab edge of at least one of the two stacks to be coupled, to bind the sheets into a book along a spine side of the sheets, the device comprising: two stack holders to each hold a stack of at least one sheet, a cutting assembly to perform the process of cutting out sheet material to form the tabs, a coupling assembly to couple the tabs of two respective stacks to produce the book, in which the stack holders serve as positioners for the two stacks to keep the stacks properly oriented during the binding process at all times.

A method for providing a nonlinear line of weakness on a web material includes: providing a counter component comprising a nonlinear shape, where the nonlinear shape has a shape width, W; providing a blade in operative relationship with the counter component and comprising a plurality of teeth; rotating at least one of the blade and the counter component into interacting relationship with the other of the blade and the counter component; feeding a web between the counter component and the blade such that while in interacting relationship the blade cooperates with the counter component to perforate the web, wherein the web is moving in a machine direction; and reciprocally shifting one of the counter component and the blade for a distance, D, in a shifting direction, wherein D is at least the translational distance that one tooth travels to cover the shape width, W.

A packaging wrapper is made of material having inner and outer laminate structures bonded together. A peelable flap is defined in the wrapper by means of offset score lines in the laminate structures, the structures being bonded together in a marginal region between the score lines by means of a peelable adhesive. In one aspect of the invention, the score lines are formed using a pair of contra-rotating die cylinders positioned on opposite sides of the laminated film Each cylinder contacts a respective laminate structure and has a blade for forming a score line in that structure. In another aspect, the laminate structures are bonded together using a single peelable adhesive both within and outside of the marginal region. In a further aspect, the structures are not bonded together in at least part of the marginal region to provide a lifting tab for the flap.
