Abstract (en)

[origin: EP0329000A1] A device for braking the slide of a press, which is used in particular for the compression moulding of fibre-reinforced plastics and whose slide is acted upon by at least two hydraulic counter- holding cylinders (2) which are preferably actuated in parallel, can be used to achieve a time reduction in the closing stroke of the press if there is connected between the slide and each counter-holding cylinder (2) a resettable hydraulic shock-absorbing unit (cylinder 7 and damping plunger 9) which is active over a defined stroke by throttling and whose damping force is set smaller than the force of the counter-holding cylinder (2). <IMAGE>
