Abstract
Abstract A machine for the coupling of a fabric with a stiffening or reinforcing interlining by means of interposition of an adhesive layer, including a compressing device and a heating device, the improvement residing in the fact that the compressing device consists of a Teflon felt carpet, which winds and slides in contact with three rollers having their respective axes disposed on the same vertical line and which is subtended by a front roller, maintained in tension by a pair of either pneumatic or hydraulic cylinders, the lower roller of said three rollers being pushed to the central roller with a variable pressure and the central roller having a large diameter than that of the other two rollers, the fabrics having to undergo the treatment being fed to the machine between the central roller and the carpet, and the heating device consists of two series of infra-red ray heaters, contained in the casings disposed laterally to the central roller, and the temperature being checked by a probe maintained in contact with the central roller in an area in the vicinity of the entrance zone of the fabric to be treated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
200 words
IN A MACHINE FOR THE COUPLING OF A FABRIC WITH AN INTERLINING BY MEANS OF THE INTERPOSITION OF AN ADHESIVE LAYER INCLUDING A COMPRESSING DEVICE AND A HEATING DEVICE, SAID COMPRESSING DEVICE INCLUDING: UPPER, CENTRAL AND LOWER ROLLERS WITH AXES FIXEDLY DISPOSED IN THE SAME PLANE, A GUIDE ROLLER DISPLACED FROM THE PLANE OF THE SAID UPPER, CENTRAL AND LOWER ROLLERS, A CONTINUOUS BELT DISPOSED ABOUT THE SURFACES OF SAID UPPER AND LOWER ROLLERS ON ONE SIDE OF SAID PLANE AND ON THE SURFACE OF SAID CENTRAL ROLLER ON THE REMAINING SIDE OF SAID PLANE, SAID LOWER ROLLER BEING THE DRIVE ROLLER FOR SAID BELT, MEANS FOR YIELDING URGING SAID FRONT ROLLER AWAY FROM SAID CENTRAL ROLLER WHEREBY SLACK IN SAID BELT IS TAKEN UP, SECOND MEANS FOR YIELDING INGLY URGING SAID LOWER ROLLER TOWARD SAID CENTRAL ROLLER WHEREBY THE FABRICS TO BE COUPLED HAVING BEEN RECEIVED BETWEEN SAID BELT AND SAID CENTRAL ROLLER IS MAINTAINED IN CONTACT THEREWITH; AND SAID HEATING DEVICE INCLUDING: TWO INFRA-RED RAY HEATERS DISPOSED ON OPPOSITE SIDES OF SAID CENTRAL ROLLER; A PROBE IN CONTACT WITH SAID CENTRAL ROLLER INDICATING THE TEMPERATURE THEREOF AND AN EXIT CONVEYOR WHICH IS CONTINUOUS AND TANGENTIAL WITH SAID BELT.
Claim 2
Dependent Claim
