Abstract
On a sectional warping machine, the dividing-shed formation for introducing a dividing element is controlled in such a way that at least one yarn sensor (18, 18') is introduced transversely to the running direction of the shed warp (11, 12) into the opened dividing shed (15). The yarn sensor generates a control signal on detecting an incorrectly arranged yarn (34) in the feed area. The yarn sensor is preferably introduced into the dividing shed (15) together with a motor-driven element transporter (13), wherein the drive of the element transporter can be switched off and/or reversed by the control signal.
Claims13
In a method of controlling a dividing-shed formation in a sectional warping machine, said method comprising steps of opening a yarn warp to form a shed defined by two shed warps, and introducing a dividing element for demarking the shed warps, the improvement comprising a step of, prior to the introducing step,
- moving at least one yarn sensor into the shed in a direction transverse to the yarn warp, and
- generating a control signal upon detection of a yarn in the vicinity of the sensor.
A device for controlling a dividing-shed formation on a sectional warping machine of the type in which the yarn warp can be opened up to form a shed into which a dividing element can be introduced to demark shed warps, said device comprising at least one mobile yarn sensor adapted for introduction into the opened shed in a direction transverse to the warp yarns, said yarn sensor being adapted to generate a control signal upon detecting a yarn in its vicinity.
