Title: Improvement in textile printing apparatus
IPC: B41F22/00
Filed: 1943-10-09
Abstract: 577,635. Feeding webs. TRIGGS W. W. (Rice Barton Corporation). Oct. 9, 1943, No. 16563. [Class 100 (i)] [Also in Group XXXV] Textile printing apparatus comprises a supply roll 11 driven by an independent motor 30 the speed of which is automatically regulated to unwind the cloth 10 at the same rate as that at which it moves through the printing zone. The printing rolls 18 are of indeterminate size, due for example to wear, and the cloth is driven through the printing zone by a constant speed motor 24 associated with a printing roll so that the cloth speed is determined by the size of the roll. A drag roll 120 preferably engages the fabric as it enters the printing zone and drives one member 123 of a differential gear a similar member 125 of which is driven from one of a pair of rolls 32 supporting and driving the supply roll and driven by the motor 30. The third member of the differential gear actuates a rheostat in the field circuit of the motor 30 to match its speed with the speed of the fabric entering the printing zone. The rheostat arm may be actuated through a friction clutch to prevent damage if overdriven. An alternative differential mechanism comprises an internally screwed member coupled to the rheostat arm and threaded upon a screw, the screw and screwed member being driven in like senses by the drag roll and driving roll respectively. The apparatus may have a second supply roll 15 for a gray back cloth which is also driven by the motor 30. The printing material may pass over drying rolls 84 to a winding roll 87 and the back cloth may pass to another winding roll 90 or be constituted as an endless band. The winding rolls 87, 90 may be driven by another motor 88 which is controlled in like manner to the motor 30. To ensure feeding of the end portion of cloth at a controlled rate whilst a new supply roll is being introduced and joined to the fabric off the old roll supplementary rolls 60, 61 are coupled with the controlled motor 30. The tension on the material may be maintained constant by suitable means such as dynamo-electric machine TM coupled to tension rolls 77 and automatically regulated to constant current. Rheostats in the shunt field circuits of the machines 24 and T.M. may be coupled together to co-ordinate the operation of the machines.
