Abstract
A Jacquard emulator for operating the pins of a Jacquard mechanism as is used in the textile industry. The emulator has a number of disks mounted on the shafts of respective stepper motors. The disks have a number of holes therein so that when the disks are brought into contact with the pins by axial movement, predetermined pins align with holes in the disk so that required patterns of pins are actuated. The stepper motors are controlled to orient the disk to vary the pattern of pins actuated as required by a desired program.
Claims6
Apparatus, for use in a textile machine having a Jacquard mechanism of the type having elongate pins extending along a mutually parallel pin axis and terminating in pin ends, for actuating predetermined patterns of the pins in accordance with program data, said apparatus comprising:
- at least one disk mounted on a respective shaft for rotation about a shaft axis which extends parallel to the pin axis;
- said at least one disk having a face which is position adjacent the pin ends and which is formed with axially extending holes arranged at predetermined locations;
- and
- means for rotating said at least one disk about the shaft axis to orientate the at least one disk such that the holes are aligned with predetermined ones of the pin ends in accordance with the program data.
