Abstract
A device for the recognition and readjustment of variations in the cylindrical yarn deposit at the insides of flanges (23,23') of warp beams or sectional warp beams (24) in warping machines has two sensor heads (4,4') with three sensors (1,2,3;1',2',3') at each flange (22,22') and the corresponding switching and control devices.
Claims5
A device for controlling the take up of yarn on a beam with a movable reed, and comprising
- at least one sensor head mounted on a holding device, said sensor head having a first, a second and a third sensor with each connected by an electrical line to a programmable control means,
- said second and third sensors extending at an angle of 90.degree. with respect to each other and said first sensor extending at an angle of 45.degree. with respect to both said second and third sensors,
- said holding device being carried on support means for moving said holding device along a first and a second axis which extend perpendicularly to one another, said support means including first and second motor means each for effecting movement along one of said axes of said holding device, said motor means being connected to and operated by said control means,
- a first reed moving motor for moving said movable reed parallel to said beam and a second reed motor for adjusting the lap width of said movable reed, said reed motors each being connected to and controlled by said control means.
