Abstract

A cutting head for monoguide cutters, with a self-adjusting device is provided. The self-adjusting device can include sets of bearings that comprise fixed bearings ( 31, 32 ) and an adjustable bearing ( 33 ) that act on races ( 11, 12 ) of a monoguide profile disposed on different planes. Each adjustable bearing ( 33 ) is mounted on a rocker arm ( 4 ) with a first end ( 41 ) rotatably mounted on a shaft ( 5 ) fixed to the cutting head ( 2 ), and with a second end ( 42 ) that presses against an elastic element ( 6 ) situated between the second end ( 42 ) of the rocker arm ( 4 ) and the case of the cutting head ( 2 ), the elastic element ( 6 ) determines the pressure of the bearings ( 31, 32, 33 ) against the races ( 11, 12 ) of the monoguide profile ( 1 ).

First claim

The invention claimed is:

1. A device for monoguide cutters, comprising:
a cutting head configured to move along a rail having a single profile, which includes two sets of bearings on opposite sides of the rail, each set of the two sets of bearings comprising two fixed bearings and one adjustable bearing;
wherein the two fixed bearings are longitudinally aligned and separated in a direction of movement of the cutting head; and
wherein the adjustable bearing is arranged between the two fixed bearings on a plane perpendicular to the two fixed bearings;
wherein the two fixed bearings and the adjustable bearings act on longitudinal races defined on the rail and arranged on different planes; and
wherein each of the adjustable bearings is mounted on a rocker arm which has a first end rotatably mounted on a shaft fixed to the cutting head, and a second end that presses against an elastic element situated between said second end of the rocker arm and a case of the cutting head, said elastic element determining a pressure of the adjustable bearings against the longitudinal races of the monoguide profile.

2. The device according to claim 1 , wherein the the two sets of bearings are located on an inside of the cutting head.
