A method of making a cork drum (16) for high speed cigarette making machinery wherein a cork drum (16) is run hot for accelerating the setting rate of the tipping glue. The cork drum (16) is heated to operating temperature and machined while hot. This provides a drum surface that is true to desired form at operating temperature. Knives (20), which mate with the surface of the drum for cutting tipping paper therebetween, are ground with an edge, which is slightly concave. A method and machine for cutting cork tipping paper at high speed utilizing a heated drum (16), carbide drum inserts and mating cutting knives.

The present invention provides a method of manufacturing a pneumatic tire which includes an inner liner layer formed of a laminated sheet obtained by laminating: a sheet made of a thermoplastic resin or a thermoplastic resin composition obtained by blending a thermoplastic resin and an elastomer; and rubber cured and adhered to the thermoplastic resin or the thermoplastic resin composition and in which no crack develops around a splice portion of the inner liner layer after the start of usage for running, the pneumatic tire thereby being excellent in durability. The method of manufacturing a pneumatic tire uses the laminated sheet having a predetermined length and the inner liner layer is formed from the laminated sheet through a step of cure-molding the tire with end portions of the laminated sheet lap-spliced. In the method, when at least the sheet made of the thermoplastic resin or the thermoplastic resin composition obtained by blending the thermoplastic resin and the elastomer is cut into the predetermined length, the cutting is performed by using an edge tool having a non-sharp edge under a temperature condition not lower than 60°C and not higher than a melting point of the thermoplastic resin.

The invention relates to a method and system for the mechanical-thermal separation of different materials such as textile flat structures, threads, and plastic films by heating and simultaneously compacting the material. According to the invention, the material is fed through a gap which is formed between a tool (2) and an opposing surface (3) that touches the tool while forming a point. An adjustable electrical current is conducted over the contact point (5) in such a manner that a temperature profile (14), which is adapted to the density of the material, in the area of the contact point (5) is set such that the temperature of the tool (2) and opposing surface (3), independent of their shape and cross-section up to the contact point, is, in the advance direction of the material (1), increased to the same maximum value, and the contact point is heated in a defined manner.

Disclosed is a separating device (1) for cutting profiled plastic elements, comprising a work bench (2) across which the profiled plastic element is guided. A metallic cutting knife (5) is driven relative to the work bench (2). A heating apparatus (14) that encompasses a power source (18) is used for heating the cutting knife (5). The heating apparatus (14) is equipped with a heating induction coil (15) that is spaced apart from the cutting knife (5). The power source (18) is provided with an electrical supply unit for feeding a voltage to the induction coil (15). A separating device (1) which does not necessarily comprise a metallic cutting knife (5) and does not necessarily encompass a heating induction coil for heating is fitted with a temperature sensor (27) for detecting the temperature of the cutting knife (5). The respective separating device has an improved cutting performance.
