Abstract: An apparatus for forming shaped bodies from a thermoplastic film has a stationary support, a downwardly directed upper tool fixed on the support, means for feeding the film in a transport direction in steps underneath the upper tool, a lower shaft pivotal in support below the traverse, a frame carried on the shaft and pivotal therewith about an axis of the shaft, an upwardly directed lower tool shiftable on the frame toward and away from the axis, a pair of arms extending radially from the shaft, a link extending between one of the arms and the lower tool, and a crank drive element. A connecting rod extends between the other of the arms and the crank drive element. A stationary cam adjacent the frame has a nonstraight cam formation, and a cam follower on the tool engages the cam formation. A drive rotates the crank drive element.

Abstract: A stacking apparatus for a thermoforming machine with a guide bar for a slider of a pivot arm which can be swung between positions along the pivot arm to pick up containers or covers and to deliver stacks of the containers in horizontal orientation to a receiving plate or conveyor. In another position of the guide bar, the pivot arm delivers the stacks of articles to the receiving table or conveyor in upright columns.

Abstract: An apparatus for manufacturing and stacking deep-drawn articles of thermoplastic synthetic material or the like includes a heating unit, an intermittent foil transporting unit, a rigid upper tool, and a raisable and lowerable as well as pivotable lower tool, wherein the movements of the lower tool are determined by cam discs mounted on a drive shaft and by cam rollers for the cam discs, and a stacking device. The lower tool is arranged linearly movably guided in a pivoted bracket.

Abstract: A stacking apparatus for deep-drawn articles of plastics material, particularly articles manufactured in a thermoforming machine, includes a lower stacking plate and an upper stacking plate which are adapted to receive formed articles from the forming die of the thermoforming machine. The lower and upper stacking plates are used to form a vertical stack of formed articles. The upper stacking plate, including a stack of formed articles carried by the upper stacking plate, can be raised to a position on the working level of a removal station.
