ABSTRACT:
The device includes a compression stand on which a food can is placed and which is driven with vertical translation motion by a telescopic rod under the control of a cam-follower roller engaged in a cam track. During the upstroke of the rod, its two component elements are hydraulically locked together by the presence of oil in an intermediate chamber that is closed. At the top end of the stroke, the oil can escape through a passage, thereby releasing a spring which determines the force with which the can is pressed against the stationary mandrel while the lid is actually being crimped thereon.
