Title: Improvements in or relating to nap raising machines
IPC: D06C11/00
Filed: 1956-06-14
Abstract: 816,441. Automatic tension control systems. ETABLISSEMENTS A. C. SCHOLAERT. June 14, 1956 [June 23, 1955], No. 18385/56. Class 38 (4). [Also in Group XVI] A nap-raising machine comprises a roller provided at the exit from a raising drum, the roller having means for adjusting the linear speed of the fabric passing thereover, and a control member which is movable up and down in response to the length of a falling loop formed in the fabric between the raising drum and the roller and connected to the means for adjusting the linear speed of the fabric so that any increase or decrease of the length of the loop causes an increase or decrease of the linear speed of the fabric whereby the length of the loop remains substantially constant, and the tension of the fabric at the exit from the raising drum is practically nil. As shown, fabric 6 is passed through a nap-raising machine having napraising drums 2, 3 driven in synchronism by an electric motor 5. The fabric is fed by a feedroller 9, driven by an electric motor 11 provided with a speed control 12 actuated manually by a knob 13, passes around guide rollers 14, 15, over rollers 16, 17 carried by an arm 18 coaxial with the drum 2, and then forms a loop around a bar 21. The bar 21 is carried by two arms 22 mounted on a shaft 23 carrying a gear sector 37 meshing with a pinion 38. Movements of the bar 21, in response to variations in loop length, cause the pinion 38 to vary the setting of a potentiometer, not shown, connected to the speed control 12, thus varying the speed of an electric motor 25 driving a feed roller 24. The length of loop around the bar 21 and thereby the tension of the fabric 6 may be controlled. A bar 31, engaging a loop on the exit side of the second nap-raising drum 3, similarly controls the speed of an electric motor 35 driving a feed roller 34 to maintain constant tension in that part of the fabric.
