摘要： 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.

摘要： The invention relates to a method for introducing foam material (3) into hollow chamber profiles, in particular hollow chamber profiles for windows or doors. An extrusion process is used to shape the hollow chamber profile (1), which has at least one hollow chamber (2, 2'), wherein at least one reinforcement strip (6) is arranged on at least one wall of at least one hollow chamber (2) which is to be filled by foaming. Then, foam material (3) is introduced into the hollow chamber (2) to be filled, wherein the reinforcement strip (6) avoids deformation of the hollow chamber (2) on account of the excess pressure which arises during the foaming operation. The invention also relates to a hollow chamber profile (1).
