Abstract: A method for producing a composite part from a first molded part and a second molded part via injection molding, injection compression molding or back compression molding of a plastic material, includes the following steps: producing the first molded part from a first plastic via such molding of the first plastic such that the first molded part features at least one elevation on one side, removing a segment of the first molded part and arranging the second molded part on the first molded part instead of the removed segment so that the respective elevation is situated on an edge of the second molded part, and applying a layer of a second plastic on the second molded part on the side facing away from the first molded part via injection molding, injection compression molding or back compression molding of the second plastic.

Abstract: The invention relates to a method for producing a composite part from a first moulded part (10) and a second moulded part (15) by the injection moulding, injection compression moulding or back compression moulding of plastic material.

Abstract: The closure device is intended to hold the free end of an elongated element on a winding collected on a winding station during the operations of making ligatures on this winding. The device includes a support, capable of being set in rotation about a shaft coaxial with the winding, and two means of actuating bent arms, pressing portions of which are capable of clamping the last layer of the winding. This device makes it possible to automate the finishing operations of the winding. Furthermore it makes it possible to aid in discharging the finished winding from the winding station.

Abstract: The drum (5) is at the station of wrapping and extraction of a coil of material wound on the segments (16) and bounded by the radial arms (24 and 21). Once the wrapping film has been placed about the coil of material and the arms (24 and 21), the cross-piece (17) is advanced so that the arms (21) are overturned backward and can be extracted from the front inner edge of the wrapping. Next, the pushers (28) move the wrapped coil of material by pressing against the rear flank of the wrapping between the arms (24). The latter pivot towards the front against the bias of the springs (26) so that their outer ends also pass under the inside edge of the rear flank of the wrapping. When the jack (19) returns the cross-piece (17) to its starting position, the arms (21) are righted by the action of the ramps (23). This device permits choosing the inside diameter of the coils of material at will, without being hindered by the presence of the radial arms (21).
