摘要： A thermoforming machine utilizes two clamping frames to advance cut sheets through heating and forming stations, with the clamping frames returned via an overhead path above the oven in the heating station. Pneumatic cylinders arranged about the inner perimeter of the frames are operated to grip the sheet and release the sheets, which are pressurized and released via fluid connections established when the frames are lifted from a transfer bar structure at the loading and forming stations. The clamping frames have pivoted end sections which are engaged by extendible gear posts at the forming station to bend the clamped sheet into greater conformity with the tooling shape prior to forming.

摘要翻译：热成型机使用两个夹紧框架来通过加热和成型站推进切割片材，夹紧框架通过加热站中烤箱上方的架空路径返回。围绕框架的内周布置的气缸被操作以夹紧片材并释放片材，片材通过当框架在装载和成形站处从转移杆结构提升时建立的流体连接被加压和释放。夹紧框架具有枢转的端部部分，其在成形工位处由可延伸的齿轮柱接合，以在成形之前使夹紧的片材与工具形状更加一致。

摘要： A thermoforming press in which the shut height of upper and lower platens is adjustable by a keyed connection between a press frame top assembly and each of four posts of the frame established by pieces which are movable and which also act as cams to raise or lower the frame top assembly, moving the upper platen therewith to vary the shut height. The movable pieces are moved in unison by a drive motor to insure uniform movement of the frame top assembly. The platens are driven by rotary crank plates, which are in turn driven by rotary output shafts of right angle drives. Pairs of rollers engage the perimeter of each crank plate on one side to resist bending loads on each shaft.

摘要： An indexing system for synthetic plastics molding machinery, wherein plastic web gripping drive elements are employed to feed a plastic web in planar indexing movements to the molds of the machine, utilizes a conventional pump driven hydraulic motor connected with the web gripping drive elements by drive transmission mechanism incorporating a brake for positively halting the web gripping elements in predetermined position. A stroke measuring control device driven by the drive transmission mechanism in a path of movement corresponding with the indexing moving of the web gripping elements first decelerates the movement of the web gripping elements and then positively halts them in a predetermined position. Alternatively, a photoelectric eye sensitive to the position of the web can stop the web.

摘要： A mechanism for clamping a web of thermoplastic material against the face of a female mold prior to closure of the mold includes a clamping ring assembly mounted on the machine frame for movement relative to the frame independently of the molds. The clamping assembly is driven to and from its web clamping position by a cam mounted on the rock shaft which drives the molds between their open and closed positions and a constant radius section on the cam holds the clamp in its clamping position throughout a substantial portion of the operating cycle.

摘要： Method and apparatus for trimming an article integrally differentially pressure formed in a sheet of thermoplastic material comprising a pair of trim dies which are relatively moveable between spaced apart positions for receiving a sheet carrying an article to be trimmed, closed positions, engaging opposite sides of the sheet, and then to sheet severing positions in which an article is severed from the sheet. The dies are relatively moved via a wedge which is transversely moveable on the machine and includes a first sharply inclined wedge surface for rapidly advancing the trim dies from the spaced apart positions to the closed positions. A second, less inclined wedge surface, which is a continuation of the first wedge surface, is provided for moving the trim dies from the closed positions to the sheet severing positions. Servomotor driven crank mechanism is provided for selectively transversely concurrently moving the wedges in opposite direction through selected lengths of travel to selectively move the trim platen to any selected one of a plurality of different strokes between the open positions and the closed positions.

摘要： Stacks of generally dish-shaped, nested plastic articles are gripped and transferred from elevated, horizontally adjacent chutes comprising circumferentially disposed, axially extending supports, which are open at both ends to permit articles to be both fed thereto and removed axially therefrom, to a conveyor disposed at a lower level. A transfer arm, mounting stack gripping receivers, which pivot on the transfer arm, is swung in an arcuate path and the receivers are moved relative to the transfer arm, responsive to swinging movement of the transfer arm, such that the receivers travel from a first position, horizontally axially aligned with said chutes and axially intermeshed with the supports, in a path having a first axially linear increment, then a downward arc to rotate said stacks substantially 90.degree., and finally a vertically linear path to deposit the stacks on the conveyor. The receivers are radially contracted to peripherally grip stacks of articles in the chutes when the receivers are in the first position, and are radially expanded to peripherally release the stacks when the receivers have moved the stacks to the conveyor.

摘要： A thermoforming machine having opposed mold platens includes a linkage system driven in cyclic movement by rotary cam mechanism to cyclically shift the platens between their open and closed position. The cam mechanism is driven by a variable speed motor which is controlled in a manner such that the rotary speed of the cam mechanism during different portions of a cam revolution may be set to a speed which is different than the rotary speed of the cam mechanism during other portions of each revolution. By adjusting the speed differential or by adjusting the angular extent of that portion of a revolution of the cam mechanism over which the different speed is maintained the time duration of any chosen portion of the cycle may be adjusted independently of the time duration of other portions of the cycle.
