Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zum Durchtrennen von endlosen Profilen mit einer Längsachse, insbesondere von extrudierten Kunststoffprofilen, mit einem Messer, das in Richtung der Bewegung des Messers auf das Profil zu und im wesentlichen senkrecht zur Längsachse bewegbar ist.The invention relates to a device for severing endless profiles with a longitudinal axis, especially of extruded ones Plastic profiles, with a knife pointing in the direction of movement of the knife towards the profile and essentially perpendicular to the longitudinal axis is movable.

Erfindungsgemäß sind Mittel (3, 4) zum Biegen des Profils (2) entlang seiner Längsachse (L) im Schnittbereich des Profils (2) vorgesehen, wobei die Mittel (3, 4) durch die Biegung in dem dem Messer (5) zugewandten Bereich des Profils (2) eine Zugspannung erzeugen.According to the invention, means (3, 4) for bending the profile (2) are along its longitudinal axis (L) is provided in the section of the profile (2) the means (3, 4) by the bend in the knife (5) facing Area of the profile (2) generate a tensile stress.

Die Erfindung geht dabei von der Erkenntnis aus, daß bei vorbekannten Trennvorrichtungen durch das in das Profil eindringende Messer dieses bei eben aufliegendem Profil eingeklemmt wird, da nicht wie bei einer Säge ein Freiraum für das Messer ausgeschnitten wird. Die Erfindung wirkt der entstehenden Klemmkraft entgegen.

Figure 00000001
The invention is based on the knowledge that, in the case of previously known separating devices, the knife penetrating into the profile causes the knife to be clamped when the profile is lying on it, since a free space for the knife is not cut out like in a saw. The invention counteracts the resulting clamping force.
