Abstract
Abstract A gripping arrangement for removing laminated circuit boards from the lamination region of an automatic laminating apparatus includes a gripping element which grasps the board after a predetermined portion has emerged from the apparatus. A carriage is simultaneously actuated to impose a displacement force on the laminate to assist in withdrawing it from the apparatus.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
207 words
In an apparatus for applying a resist material to a planar member to form a laminate as the member is advanced therethrough, the laminate being subjected to a restraining force within the apparatus, a gripping arrangement for removing the laminate from the apparatus comprising: a carriage movable under the influence of a predetermined displacement force from a first to a second position; a first actuator for applying a predetermined displacement force on the carriage; a gripping element mounted to the carriage, the gripping element being movable from an open to a grasping position; a second actuator for moving the gripping element from the open to the grasping position; a detector for generating a signal representative of the emergence of the laminate from the apparatus; and, means responsive to the signal for simultaneously energizing the actuators to move the gripping element to the grasping position and initiating the application of the displacement force to the carriage, the magnitude of the displacement force being such that it is dominated by the restraining force until the laminate is advanced completely through the apparatus, the displacement force thereupon becoming dominant to apply a jerking force to free the laminate from the resist material and displace the carriage to the second position.

Dependent Claim

Claim 3
Dependent Claim
87 words
The gripping arrangement of claim 1 wherein the gripping element comprises: a housing; a grasping member movable in the housing from the open to the grasping position, the grasping element having an opening therein; and a lever connected to the second actuator, the lever having an array of rollers thereon, the rollers being displaced within the opening such that the force imposed by the second actuator on the lever is equally applied to the grasping member to prevent point contact between the grasping member and the laminate.
