Abstract: An installation for sorting out reject slugs out of the slug channel of an automatic coining machine with a slug control mechanism, whereby the reduction of the reaction time for the rejection of slugs to be sorted out permits a considerable increase of the number of coining strokes of the automatic coining machine, without the need for a further additional intermediate storage of slugs. The reject channel for rejected slugs is thereby kept closed by shaped members in the manner of shutters and is opened up in case of need whereby also the desired dimensions for the slugs are determined by the shaped members. Such a slug control mechanism is needed in the slug channel of an automatic coining machine in order to separate good slugs from reject slugs.

Abstract: An apparatus for the intermittent feeding of web-type or strip-type material by means of feed roll into an operating chamber of a press. The feed rolls are driven by a main press drive through a mechanical connection and a feed gear mechanism. A scrap cutter is provided which can be driven in correspondence with the operating cycle of the press. The mechanical connection can be selectively severed or interrupted with an auxiliary drive mechanism being provided which is adapted to be connected to the apparatus. The scrap cutter may be driven by a separate drive mechanism in correspondence with the cycle of the feed gear mechanism.

Abstract: Press apparatus including a blank holding ram and a drawing ram which are reciprocally driven such that the holding ram can hold a blank of material while the drawing ram moves relatively to the holding ram to perform a drawing operation on the blank. Stops are provided for limiting the movement of the holding ram with pressure fluid cushions being arranged in the drive train for the holding ram so as to accommodate a dwell phase with the holding rams against the stops during the drawing operation.

Abstract: Apparatus for stripping hollow articles off of a press ram including a stripper supporting ring extending circumferentially around the press ram, a plurality of segments mounted on said supporting ring for limited radial displacement with respect to the press ram axis, and a plurality of individual hydraulically cushioned strippers mounted in each of said segments for direct engagement with the article to be stripped from the press ram. Various preferred embodiments include various mechanisms for permitting and/or positively providing radial displacement of the segments so as to accommodate passage of the press ram and article to be stripped. Several of these preferred embodiments include biasing means such as springs and/or pressure medium forces for biasing the segments radially inwardly and chamfered conical beveled edges on the segments for accommodating an outward biasing force application by way of the article and press ram.
