Close film cutters
while load on hydraulic
cylinders is identical
When the load on the hydraulic cylinders is identical, the control rams (1,
4) are subject to equal loads.
The compression springs position the two control rams so that the
opening cross-sections of the bores (2, 3) are identical.
The equal partial volume flows (ports P2, P3) are combined into one total
volume flow (port P1).
The film cutters close with the same speed.
