Abstract

A slitting machine having at least two knife holders, with a respective knife rotatably mounted on each knife holder. Individually activatable electromagnetic sensors are disposed on the knife holders, and a single magnetostrictive rod extends through a portion of all of the electromagnetic sensors. A unit processes interrogations by the rod of activated ones of the electromagnetic sensors for indicating the position of at least one of the knife holders relative to the rod.

Claims

1. A slitting machine, comprising:

at least two knife holders (22), each of which has a respective knife (23) rotatably mounted thereon;

individually activatable electromagnetic sensors (24) disposed on said knife holders (22);

a single magnetostrictive rod (25), wherein said electromagnetic sensors (24) are also disposed along a length of said rod; and

means for processing an interrogation by said magnetostrictive rod (25) of activated ones of said electromagnetic sensors (24), and for indicating the position of at least one of said knife holders (22) relative to said rod (25).

2. A slitting machine according to claim 1, wherein each of said electromagnetic sensors (24) has a C or U shaped portion that extends about said magnetostrictive rod (25).

3. A slitting machine according to claim 1, wherein said electromagnetic sensors (24) are activatable in groups.
