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.

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： An oscillating canopy is employed in the feeding of an elongate sheet of synthetic plastic material having articles, such as cups, for example, formed in the sheet, to a die which trims the articles from the sheet. The canopy has a downwardly concave curved upper portion upon which the sheet is supported by a series of rollers. The canopy is driven in forward and return strokes in pivotal movement about an axis located at a radial distance from the curved upper portion which is a greater distance from the discharge end of the curved upper portion than from the sheet receiving end so that tension is maintained on the sheet during the feeding stroke. The sheet-supporting rollers are mounted for rotation in one direction only, this direction being that in which the rollers can roll relative to the sheet on the return stroke of the canopy.

摘要： A thermoforming machine having opposed mold platens includes a linkage system driven in cyclic movement by a single rotary cam to cyclically shift the platens between their open and closed position. The cam is driven by a variable speed motor which is controlled in a manner such that the rotary speed of the cam during different portions of a cam revolution may be set to a speed which is different than the rotary speed of the cam 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 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. The platens are mounted for reciprocatory movement upon a three-post frame.

摘要： A trim press for severing cup-shaped articles from a sheet of thermoplastic material in which the articles have been integrally formed as by a vacuum forming operation. A horizontally reciprocable punch is driven to sever articles positioned in a stationary die by a linkage arranged to drive the punch at a relatively slow speed during the severing operation to achieve a smooth shearing separation of the relatively soft thermoplastic material. The sheet is fed into the die in step-by-step movement through vertical sheet guides fixedly mounted in a treadle which is reciprocated with the punch at a proportionate speed. A flexible sheet guide connected between the guides in the treadle and a fixed point on the machine frame flexes to accommodate reciprocation of the treadle while continuously guiding the sheet to the guides on the treadle. Feed fingers mounted on the treadle advance the sheet to the die in step-by-step movement synchronized with the stroke of the punch.

摘要： A differential pressure thermoforming machine has a female mold with a female mold cavity, and an opposing mold, with a mold closing portion cooperable therewith. A foam injection head is perimetrally separated from the mold closing portion and is provided on the opposing mold. When the molds are initially closed, a differential pressure is created in the molds to cause the heated plastic sheet to move into contact with the mold cavity and form a configured pocket in the sheet. Mechanism is provided for releasing the plastic sheet from the carriage in which it has been moved between the molds, after the molding operation, to the cavity in the female mold, after which the molds are restored to spread-apart position. Mechanism is then activated to move the opposing mold to a position in which the foam injection head is now aligned with the female mold, whereupon the molds are again closed to bring the injection head into the pocket, whereupon the foam injection head is operated to charge a settable foam material to the pocket formed.

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： 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.
