Abstract:
Es wird ein Werkzeug zum Greifen, Platzieren und Drapieren eines Faserzuschnitts (11) für eine lokale Verstärkungslage im Zuge der Herstellung eines dreidimensionalen Vorformlings für die Herstellung von faserverstärkten Formteilen vorgeschlagen. Das Werkzeug (1) weist zumindest ein Greifelement (4), insbesondere ein Vakuumgreifelement, zum Greifen und Aufnehmen des Faserzuschnitts (11), und zumindest ein Drapierstempelelement /2) zum Drapieren des Faserzuschnitts (11) auf, wobei das zumindest eine Greifelement (4) und das zumindest eine Drapierstempelelement (2) relativ zueinander verstellbar sind, insbesondere zwischen einer ersten Stellung zum Greifen des Faserzuschnitts (11) und einer zweiten Stellung zum Anformen des Faserzuschnitts (11), mittels des zumindest einen Drapierstempelelements (4), auf einen Fasergewebestapel (12). Bevorzugt kann auch eine Fixiereinrichtung (7), wie eine Ultraschall-Sonotrode, vorgesehen sein, um den Faserzuschnitt (11) auf dem Fasergewebestapel (12) zu fixieren.

Abstract:
An apparatus and method for loading a tread press are provided. More specifically, the present invention provides for loading a tread band onto a tread press while suspending the tread band above the mold elements as the tread band is moved into the proper longitudinal position within the tread press. Lateral positioning can also be provided using the present invention.
