METHOD FOR AUTOMATICALLY PIECING A THREAD AT A WORKSTATION OF A TEXTILE MACHINE, AND TEXTILE MACHINE
A method for automatically piecing a thread at a workstation of a textile machine, includes seeking an end of the thread on a surface of a bobbin with a suction nozzle and unwinding the thread from the bobbin counter to a regular draw-off direction of the thread and sucking the thread into the suction nozzle. The bobbin is driven in a direction of reverse rotation with a drive. A thread loop is draw-opened in the thread and moved towards a piecing unit via movement of a feeder unit. The bobbin is driven in the direction of reverse rotation during the drawing-open of the thread loop such that the thread is unwound from the bobbin. A speed of reverse rotation of the bobbin is coordinated with movement of the feeder unit.
DEVICE FOR PIECING A THREAD AT A WORKSTATION OF A TEXTILE MACHINE COMPRISING A SUCTION NOZZLE AND COMPRISING A FEEDER UNIT
A device for piecing a thread at a workstation of a textile machine includes a suction nozzle configured to pick up a thread end of the thread from a bobbin, the suction nozzle including an entry opening for the thread. A feeder unit is movable with respect to the suction nozzle and includes a cover element configured to close the entry opening in a first position (I) of the feeder unit and to unblock the entry opening in a second position (II) of the feeder unit. The cover element includes a thread-guiding element having an open contour.
Method for extracting a thread by suction from a bobbin and a corresponding system
A system and associated operational method are provided to extract a thread by suction from a bobbin and for re-attachment of a thread end of the thread to a new thread. The thread is extracted from the bobbin by sucking the thread in against its spooling direction on the bobbin through a suction nozzle and into an extraction port of an extraction system. A loop is subsequently formed in the thread, and the thread is separated in the area of the loop. One thread end of the separated thread is discharged into an extraction port, and the other thread end coming from the bobbin is prepared for re-attachment to a new thread. Upon being extracted by suction into the extraction system, the thread is guided through an eyelet located in a run of the thread to the extraction port and the eyelet, together with the thread, is moved out of the run of the thread to the extraction port such that the thread forms the loop between the bobbin, the eyelet, and the extraction port.
Method for Operating a Workstation of a Spinning Machine or Winder
A method at a workstation of a spinning machine or winding machine supplies an auxiliary thread from a thread nozzle to a suction assigned to the workstation, the auxiliary thread stretched between the thread nozzle and the suction. The auxiliary thread is severed to form a thread section protruding into the suction and a thread section extending into the thread nozzle, wherein the thread section protruding into the suction is carried away by the suction. The thread section extending into the thread nozzle is grasped with a thread receiver such that the thread section extending into the thread nozzle extends between the thread nozzle and the thread receiver. The thread section extending into the thread nozzle is severed to form a thread section remaining in the thread nozzle and a thread section coming from the thread receiver. The thread section coming from the thread receiver is transferred to the suction of the workstation. The thread section coming from the thread receiver is grasped with a capture arrangement adjacent a tube at the workstation prior to starting a process of winding the thread section coming from the thread receiver onto the tube.
Material holder
Material holders for use with a structure (e.g., a stand, tool box, etc.) may include material holding apparatus configured to hold a roll and/or box of material. The material holding apparatus may be configured to hold various material in an organized, open, and unobstructed manner to provide convenient access to the material.
YARN BOX, YARN STRIPPING METHOD, YARN STRIPPING APPARATUS, ELECTRONIC DEVICE
Provided is a yarn box, a yarn stripping method, an electronic device and a storage media. The yarn box includes a support, a yarn stripping rod and a yarn receiving rod; where a first end of the yarn receiving rod is connected to the support, a first end of the yarn stripping rod is slidably connected to the support, the yarn stripping rod is configured to slide to a yarn stripping position corresponding to a first yarn receiving rod among the yarn receiving rod when multiple yarn spindles are sleeved outside the first yarn receiving rod and the number of yarn spindles of the first yarn receiving rod reaches a set condition, the yarn stripping rod is provided with multiple yarn strippers corresponding to the multiple yarn spindles one by one, and the yarn strippers are configured to strip fiber yarn on outer surfaces of the corresponding yarn spindles.
Method for Extracting a Thread by Suction from a Coil and a Corresponding Device
The method in accordance with the invention serves the purpose of extracting a thread (1) by suction from a coil (3) and the re-attachment of a thread end (13) to a new thread (1), whereas the thread (1) is sucked in against its spooling direction through a suction nozzle (6) into an extraction system, a loop (14) is subsequently formed, the thread (1) is separated in the area of the loop (14), which discharges a thread end (13) in the extraction port and prepares the other thread end (13) coming out of the coil (3) for re-attachment, and is subsequently attached to a new thread (1). Upon being extracted by suction, the thread (1) is guided through an eyelet (11) located in the run of the thread of the extraction port (8), the eyelet (11) is, together with the thread (1), moved out of the run of the thread of the extraction port (8), such that the thread (1) forms a loop (14) between the coil (3), the eyelet (11) and the extraction port (8), along with a corresponding device.
Method for a Textile Machine and a Textile Machine
The method in accordance with the invention for a textile machine, in particular a spinning or a winding machine with multiple similar workstations (1), serves the purpose of delivering a thread (7) to a coil (12), laying the thread (7) on the coil (12), for winding the thread (7) on the coil (12) and for finding a thread end wound on the coil (12) by means of a suction nozzle (4), whereas the thread end is sucked in by means of an opening turned towards the coil circumference that serves as an extraction mouth (10) of the suction nozzle (4). The thread (7) runs through the suction nozzle (4) during the delivery to the coil (12), whereas it enters through an additional opening in the suction nozzle (4) serving as an inlet mouth (9) for the thread (7) and exits the suction nozzle (4) through another opening, in particular through the extraction mouth (10). A textile machine, in particular a spinning or a winding machine, features multiple similar workstations, in each case with a thread delivery device for delivering a thread (7) to a coil (12), a thread traversing device for laying the thread (7) on the coil (12), a winding device for winding the thread (7) on the coil (12) and a suction nozzle (4) for finding a thread end wound on the coil (12), whereas the suction nozzle (4) features an opening turned towards the coil circumference that serves as an extraction mouth (10) for sucking in the thread end. The suction nozzle (4) features an additional opening serving as an inlet mouth (9) for the thread (7), and the thread (7) runs through the suction nozzle (4) during the delivery to the coil (12), whereas it enters the suction nozzle (4) through the inlet mouth (9), and exits the suction nozzle (4) through another opening, in particular the extraction mouth (10).
