A thermoforming trim press has one or more connecting arms for driving a movable platen, each arm having a pivotal connection between two adjacent sections of each connecting arm which is normally locked during normal press operation whereby the movable platen is able to move further back from a normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.
A thermoformer apparatus has sheet supporting rails which are divided into sections hinged together to facilitate widening of the spacing between the rails with adjuster drive mechanism as the sheet moves through an oven to eliminate sagging of the sheet as it becomes heated. Thermoformer chains are driven by a pair of independently operable servo motors each associated with a respective thermoformer chain.

Toggle drive system for driving in a thermoforming press
A drive system for double toggle mechanisms used to move upper and lower platens with an electric servo motor-gear box drive shaft driving a crank arm arranged to drive a respective double toggle mechanism in turn connected to the platen. The drive shaft axis is located below the toggle mechanism link pivots and driven in a direction so that the motor acts to assist the double toggle mechanism in lifting the platen, reducing the servo motor peak load. The various components are arranged for symmetrical loading of the pivots concerning the toggle links to increase the evenness of the platen when being raised or lowered.
A platen drive system and method of leveling platens in a forming station of a twin sheet thermoforming machine in which each platen is driven vertically by four independently operated drive units, each having an electric servo motor, the drive units arranged in two sub sets disposed on opposite sides of an associated platen. The platen is leveled during set up by individual operation of the servo motors.
Plastics machinery comprising, continuous, inline, modular and rotary thermoforming machine and trimming machine specially adapted for use only with thermoformed parts

Method and tooling for slitting a thermoformed container and container formed thereby
An open-topped container has an outwardly turned rim extending around the open top a thermoformed body of the containers with the rim formed by a clamping ring which has one or more projections each forming an indentation into the rim. Trim tooling subsequently forms a slit through the bottom wall of each indentation able to receive a flat plastic display inserted therein.

A plug assist drive assembly for driving plug assists in a thermoforming apparatus includes a single centrally located roller screw assembly enclosed in a housing and driving a third platen mounting the plug assist with a group of guide-drive bars connected to a drive platen which is driven by the roller screw nut. The roller screw assembly is removable by removing screws holding the nut to one hub adapter, the screws accessed through an opening in the housing normally covered with a plate.
