THE PRESENT INVENTION CONCERNS AN APPARATUS AND A PROCESS FOR PREPARING A FABRIC F AND IN PARTICULAR TO REDUCE THE CONSTRAINTS THEREIN. WE REDUCE THE STRESSES IN THE FABRIC F PUT IN THE FORM OF A ROLLER B BY UNWINDING THE FABRIC FROM THIS ROLL AND SUBJECTING THE UNWINDING FABRIC TO MECHANICAL VIBRATIONS OR RESONANCE IN A RELAXATION ZONE R. TO ACCELERATE THE RELEASE OF THE FABRIC, THIS THE LATEST MAY BE, IN ADDITION, HEATED AND CROSSED BY A CURRENT OF AIR WHILE IT IS SUBJECT TO VIBRATIONS. TO DO THIS, THE APPARATUS INCLUDES MEANS 18, 20 FOR UNWINDING THE FABRIC FROM ROLL B, MEANS 22, 24 FOR UNLOADING CONTROL AND MEANS FOR ESTABLISHING VIBRATION. |
