An automatic cleaner for a pressing device has a pressing unit that can reciprocate between a pressing position and an apart position. The automatic cleaner includes a separating structure configured to separate a workpiece from the pressing unit; a cleaning member; and a drive mechanism configured to move the separating structure and the cleaning member back and forth, in accordance with movement of the pressing unit. The drive mechanism is configured to make the separating structure drop the workpiece, after being worked, from the pressing unit, and to make the cleaning member clean the pressing unit, in accordance with the movement of the pressing unit.

A radial press is provided, the radial press having a frame structure, a pressing tool, a drive unit, and a press control. The pressing tool comprises a plurality of pressing elements which are disposed uniformly concentrically around a press axis and have pressing surfaces. During the appropriate activation of the drive unit, the pressing elements can be moved synchronously as required towards or away from the press axis. To this end, at least two measured value recorders, which are connected for signal transmission purposes to a comparator associated with the press control, are disposed on the pressing tool at positions spaced apart from one another in the direction of the press axis (A). When the comparative value, generated by the comparator, of the measured values provided by the measured value recorders exceeds a tolerance range stored in the press control, an activation of the signal output unit is triggered.

A medical device includes a balloon expanded scaffold crimped to a balloon catheter. The scaffold has a network of rings formed by struts connected at crowns and links connecting adjacent rings. The scaffold has a polymer coating and is crimped to the balloon. The scaffold is rotated, or allowed to rotate during crimping to improve results from crimping, such as reduced damage to the coating.

A system for recompressing a round bale into a square bale includes a bottom platen and a fixed platen proximate the bottom platen. The system includes a transfer table to receive the round bale. The transfer table is movable relative to the bottom platen to transfer the round bale to the bottom platen and to recompress the round bale. The system includes an upper platen rotatable relative to the bottom platen and the fixed platen. The upper platen is rotatable between a first position to receive the round bale between the bottom platen, the fixed platen and the upper platen, and a second position in which the upper platen cooperates with the transfer table to recompress the round bale into the square bale.

A system for recompressing a round bale into a square bale includes a bottom platen to receive the round bale and a movable platen translatable relative to the bottom platen. The system includes an upper platen rotatable relative to the bottom platen. The upper platen is rotatable between a first position to receive the round bale between the bottom platen, the movable platen and the upper platen, and a second position in which the upper platen cooperates with the movable platen and the bottom platen to recompress the round bale into the square bale.

A briquetting machine for loose metal scraps comprises a pre-extrusion part, a re-extrusion part and a final pressing part. On the upper portion of a pre-extrusion cavity (14) of the pre-extrusion part, a pre-extrusion releasing area (15) is formed near to one side of a re-extrusion cavity (24). At the front end of a re-extrusion plunger (23) of the re-extrusion part, a lateral gap (28) is formed near to one side of the pre-extrusion cavity. The cross section of the lateral gap is a right-angled trapezoid and the lateral gap is provided with a lateral slope (29). A briquetting method for loose metal scrapes is disclosed. By way of pre-extrusion and step-by-step feeding and triggering resetting loading, not only is a certain pre-pressing effect guaranteed while the loose metal scraps are processed in each feeding and pre-pressing step, but also the stress can be transferred and released timely under the over-pressure condition, which avoids the formation of dense metal block under the over-pressure condition. Therefore a continuous, automatic and safe pressing operation is assured.

A crimper device can facilitate sheathing of a stent frame for vascular delivery. The device can include first and second components that rotate relative to each other to drive radial movement of one or more compression members of the device. The one or more compression members can direct and balance a compressive force within an aperture of the device. In use, the stent frame can be positioned within the aperture and be compacted by actuation of the compression members.
