DEVICE FOR PERFORMING AN OPERATION AT A GIVEN PITCH ON A STRIP

摘要

The invention concerns a device for performing an operation at a given pitch on a strip moving uniformly and continuously. The device comprises a first unit (1) fitted with a tool alternately describing a short section of an arc about a fixed horizontal axis (9) parallel to the axis of travel of the strip so that said tool can be caused to work periodically with a complementary component to said tool carried on a second unit (2), said first unit being connected to said second unit at said fixed axis, where both units thus secured and suspended from a fixed frame (20) are caused to move parallel to the axis of travel of said strip. Application to the perforation, cutting, embossing, notching and pricking of strips.
