(under subclass 265) Apparatus in which the resilient element or weight exerts a continuing force against an opposed moving means to return a pressure surface from the compressive stroke.

52, for presses having automatic or material triggered control of the actuating means by pressure applied to the material, said control causing reversing of the direction of
platen motion.
256, for presses of the reciprocating platen type having a platen tripped stop or reverse control of the actuation.
260+, for reciprocating platen presses with actuation releasing for quick return of the platen by rebounding from the elasticity of the material or due to a biasing force.
