In an arrangement for machining an elongate object (1), successively arranged tools (5) are in turn pressed against the object and machine the latter during movement of the object in the longitudinal direction, the object being supported by a stay (4). In this connection, the tools (5) are first moved along a rising first ramp (9), to a ridge (11) thereon, after which they start to travel down a falling second ramp (12) and in this connection are pivoted about a pivoting center located at a spacing from the object, so that they are pivoted out of engagement with the machining location. In this connection, a strip-shaped object can be slit and stretched along the strip outside at least one edge of the stay, so that openings are formed in the object in mutually laterally displaced rows along at least one long side thereof. The tools (5) are each arranged on their own chain link (6) forming part of a chain (7). |
