Abstract: In a bobbin winding machine with plural winding stations (13), a bobbin transport system for conveying bobbins to be unwound to and from the winding stations comprises a feed track (10), an oppositely located removal track (14) and plural transverse transport tracks (16) extending therebetween through an unwinding position (17) of an associated winding station. The winding station (13) has a positioning element (18), which positions and holds a transport element (11) with a spinning bobbin (12) in the unwinding position and releases it after unwinding. A device (31), preferably combined as an integral unit with the positioning element (18), is additionally associated with each transverse transport track to limit the capacity of the transverse transport track to accept only a single transport element (11) between the positioning element (18) and the removal track (14).

Abstract: A winding station of a textile machine for producing cheeses is equipped with a device for pickup and transfer of a yarn from a cop to a splicer for joining to a yarn from a cheese, the pickup and transfer device comprising an air-blowing fitting, a pivot tube and a suction fitting connectable via a gripper tube to a suction source. The suction fitting is positioned outside of the normal yarn path and a yarn control device is arranged in front of the suction fitting in the area of the normal yarn path. A yarn end loosened from a spinning cop is pneumatically conveyed to the gripper tube and is threaded into the yarn control device by means of the pivoting of the gripper tube into an intermediate position and the simultaneous pivoting of the pivot tube into an operating position. If a yarn control signal is not present, no yarn splicing attempt is made and a fresh yarn pickup attempt is immediately started, i.e.

Abstract: A yarn splicing device for textile winding machines comprises a splicer mechanism for pneumatically joining yarn ends, upper and lower clamping and cutting devices, and suction-actuated yarn placement devices for placing the yarn ends to be spliced. According to the invention, one yarn placement device is a gripper tube normally parked in a zero position upstream of the yarn travel. The gripper tube has a spring-biased, pivotable gripping flap and a yarn placement hook for simultaneously placing both the lower yarn and the upper yarn to be spliced. For that purpose, one of the gripper tube and gripper tube flap carries the yarn placement hook forwardly for manipulating the upper yarn and a yarn guide disposed between the yarn placement hook and the pivot axis of the flap for placing the lower yarn.

Abstract: A bobbin winding machine includes a multiplicity of winding stations for rewinding spinning cops. Each of the winding stations has a bobbin magazine for holding the cops and a bottle-like unwinding chamber having a bearing shaft and an arbor being pivotable about the bearing shaft. The unwinding chamber surrounds a cop being fixed on the arbor during unwinding. At least a portion of the unwinding chamber is formed by a cop chute being pivotable between a cop transfer position and an unwinding position. The unwinding chamber has a shell partly encompassing a cop during unwinding.

Abstract: A method and apparatus for controlling the yarn tension of yarn being cross-wound onto a bobbin on a textile winding machine. The amount of yarn on a supply package from which yarn is unwound is determined optoelectronically, gravimetrically or by measuring the yarn tension. The winding speed of the bobbin is adjusted in response to the determined yarn amount of the supply package so as to maintain the yarn tension substantially constant during unwinding. The winding speed of the bobbin can be controlled to follow a predetermined winding speed program which corresponds to the determined mass of the supply bobbin. To determine the yarn amount gravimetrically, the supply package is weighed by a balance device as it is conveyed thereover by a conveyor. The movement of the balance in response to the mass of the supply package can be electronically transmitted to a control device which prepositions a cam having a profile corresponding to the predetermined winding speed program.

Abstract: An improvement in a multi-station bobbin winding machine having an active cop unwinding position and replacement cop reserve position at each winding station with a movable reserve cop receptacle at the reserve position, wherein a yarn suction device is affixed at each winding station to the receptacle for disposition adjacent a nose portion of a reserve cop received thereby for locating and retaining a leading yarn end of the reserve cop, without obstructing operator access to the winding station.

Abstract: An automatic winding machine includes: a multiplicity of winding stations; a conveyor belt guided along the winding stations for supplying individual spools in axial alignment to the winding stations in a given transport direction along a given transport plane; each of the winding stations including: a run-off position and a reserve position in which respective spools are maintained in readiness, a controllable deflector for conducting spools base-first from the conveyor belt to the reserve position, a chute for guiding spools from the reserve position to the run-off position, a spool receiving trough disposed below the given transport plane and substantially parallel to the given transport direction, a controllable thread suction device, and means for shifting the spool receiving trough from a relatively flat position to a relatively upright position in which a tip of a tube of a spool in the spool receiving trough approaches the thread suction device and the spool is aligned in the chute.

Abstract: An automatic winding machine, includes a plurality of winding stations each having a bobbin unwinding location, a plurality of bobbin magazines each disposed at a respective winding station for receiving a plurality of bobbins on bobbin tubes in order with respect to their tips, the bobbins each having a thread end prepared for unwinding at a given location thereon, and a thread suction device disposed above each respective bobbin magazine having a suction opening formed therein facing the upper end of a bobbin tube of a bobbin disposed in the bobbin magazine to be transferred to the unwinding location.

Abstract: An automatic coil winding machine with a multiplicity of winding stations at which supply coil magazines with respective rotary feeders are provided, and with a loading device for loading the magazines with supply coils which are moved by transporting means to the magazines, each of the supply coil magazines having a filling location for automatic feeding, and an unloading location, and means for always storing at least one supply coil in the respective rotary feeder between the filling location and the unloading location, includes a device proximate to the filling location and actuatable for performing a function leading to prevention of overfilling a respective rotary feeder with the supply coils.
