Abstract
The present invention relates to a device for detecting, in a machine, the position of contact of two rollers of parallel axes of which at least one is mounted mobile. This device is characterized in that it comprises an elastic member mounted so as to undergo, during contacting of the two rollers, a deformation, limited by a bearing, further to the relative displacement of two elements mobile with respect to each other, and means for measuring this deformation.

A device for detecting, in a machine, the position of contact of two rollers having parallel axes, at least one of said rollers being a mobile roller mounted to move, parallel to its axis, over a frame of the machine, each of the two rollers being mounted to rotate about its axis and being borne by a respective support shaft having end parts borne by bearings, the bearings of the mobile roller being mounted to move under control of respective position-adjusting mechanisms, comprising:
- elastic means mounted relative to one of said rollers, said elastic means being adapted to undergo a deformation said elastic means being limited by a bearing, further to a relative displacement of two mutually mobile means relative to each other, and means for measuring said deformation.
A process for placing in parallel the axis of two rollers, at least one of said rollers being mobile, with the aid of a detection device, comprising the steps of:
- firstly displacing a first bearing associated with said mobile roller, located on a first side of said mobile roller, in the direction of the other roller until the mobile roller comes into contact with the other roller;
- measuring a deformation of an elastic member associated with said mobile roller, and memorizing the position attained by the mobile roller, on this first side, during contacting of the two rollers;
- displacing said first bearing, located on said first side of the mobile roller, in opposite direction, to return said mobile roller to its starting position;
- repeating these operations for a second mobile bearing located on a second side of the mobile roller, so as to measure and memorize the position of contact between the two rollers, on the second side thereof;
- and
- after having returned the second mobile bearing to said starting position, again displacing the two mobile bearings simultaneously in order to bring them both into their positions of contact measured previously, which ensures parallelism of the axes of the two rollers.
