  • Patent number: 5794885
    Abstract: A weaving loom is equipped with a trolley or several trolleys, each of which carries a cloth winding mandrel. A single drive which is either separate from the main loom drive or which derives its power from the main loom drive is provided to drive one or more fabric winding mandrels in series. The trolley with its mandrel or a plurality of trolleys take up the space conventionally taken up by a cloth beam, whereby substantial floor space on the factory floor is saved.

  • Patent number: 5238339
    Abstract: The generally vertical, rectangular base frame (10) of the machine surrounds a support grate (14) with attachment members for the flat work pieces (8). A carrier (40) is moveable along two oppositely disposed frame sides (12) over the support grate, and a carriage (45) is moveable on the carrier (40), the carriage (45) carrying a work mechanism (50) equipped with at least one work tool spindle with its work tool axis directed toward the support grate (14). Feeding or positioning of the work mechanism (50) is accomplished by means of fixed and non-rotatably attached finely threaded feed spindles and associated rotatably drivable spindle nuts. The spindle nuts are each part of an associated feed device with a numerically controlled feed motor. Each of the feed spindles is attached to an associated one of the two frame sides (12) and the associated feed device is connected with one end of the carrier (40) through a bracket (42), the involved feed motors being synchronously controlled.
