Abstract:
A thread winder includes a thread winding shaft into which a bobbin shaft is inserted so that a bobbin is detachably attached to the thread winding shaft, a rotating mechanism rotating the thread winding shaft to wind a thread on the bobbin, a thread winding shaft switching mechanism switching the thread winding shaft between a preparatory position and a winding position, a guiding member guiding the thread from a thread spool to the bobbin, a guiding member position switching mechanism switching the guiding member between a guide position and a retreat position, and a link mechanism links both switching mechanisms so that the guiding member is located at the guide position when the thread winding shaft assumes the preparatory position and so that the guide member is located at the retreat position when the thread winding shaft assumes the winding position.
Abstract:
Method for transmitting thread-specific data in re-reeling operations for the manufacture of two-thread lock stitch seams which have to be documented comprising the following steps: the bobbin taking over the thread, in particular the under-thread bobbin (10) is provided with a definite bobbin identification, in a reeling station (28), in which thread material for the under-thread is reeled from a thread stock (30) onto the under-thread bobbin (10), the bobbin identification is detected and is stored in a data storage medium (24) together with a first data record characterizing the thread material and the reeling operation, after inserting the under-thread bobbin (10) into a sewing machine (18) the bobbin identification is detected, from the bobbin identification the first data record stored therewith is determined and is assigned to a second data record concerning the sewing operation and/or the sewn product, whereupon the data set so formed is stored.
Abstract:
Fully Automatic Bobbin Winder so designed as to fully automatically wind thread continuously from one bobbin to the next bobbin at high speed. The winding operation never stopping during any of the steps of the automatic operation of wound bobbin being ejected from spindle (1) and an empty bobbin being fed to spindle (1) from a shute and loader (20). The spindles are driven by a main shaft (21) connected to a power source. Spindles are housed in a turret or rotating head (8). Turn of rotating head, movement forward and reverse of spindles for loading and ejecting bobbins and other moving parts are controlled by a cammed timer (16).
Abstract:
A bobbin winding system embodying an apparatus and method for simultaneously winding two separate bobbins independent of a sewing machine is provided. The apparatus may include a bobbin winder having a thread tree and two independent bobbin sets. Each bobbin set may provide a spindle, a spindle disc, a tension guide and a bobbin bumper. For each bobbin set, a user may removably secure a spool of strand on the spindle, wherein the strand is threaded to a bobbin removably secure to the bobbin bumper. Whereby each strand may be received by at least one guide loop of the thread tree, then received by the tension guide and then secured by the bobbin of the bobbin set. The user may adjust the height of each spool by adapting the relevant spindle disc. The bobbin winder may then separately rotate each bobbin bumper so as to pull strand from at least a portion of each spool to wind around the bobbins. The bobbin winding system provides a method of winding the bobbins independent of a sewing machine whereby the interruption to the underlying sewing project is minimized, especially for multi-colored fabrics and projects.
Abstract:
A self contained bobbin winder including at least one spool rod coupled at an end thereof to a self contained housing. Each rod is adapted to removably insert within an axially aligned aperture formed in a spool of thread. At least one bobbin rod is coupled to the housing. Each bobbin rod is adapted to removably insert within an axially aligned aperture formed in a bobbin for winding thread therearound. At least one motor is adapted to rotate the bobbin upon the activation thereof. Also included is at least one switch coupled between a power source and motor. The switch has a first actuated orientation for providing power to the motors thereby rotating the bobbin rods and a deactivated orientation for precluding power from being supplied thereto. Finally, a cutoff mechanism is included to preclude operation of the device once the bobbin is fully wound with thread.
Abstract:
All-thread bobbins for use as sources of lower thread or underthread in sewing machines are formed by winding a thread onto a slender rotary spindle which extends across a winding chamber between and into aligned openings of two end walls which flank the chamber and at least one of which is adjustable axially of the spindle to vary the length of bobbins. The rotating spindle draws thread from a spool or from another suitable source of supply. When the bobbin in the chamber is fully grown, the spindle is extracted from the opening of one of the end walls and from the chamber and the distance between the end walls is increased to permit evacuation of the fully grown bobbin, e.g., by gravity. The thread between the source and the evacuated bobbin is engaged by tongs extendable into the chamber through the opening of the one end wall, and the thus engaged portion is looped and maintained in the opening of the one end wall in a position of readiness for engagement by and for winding around the spindle after the latter is again moved across the empty chamber and into the opening of the one end wall to proceed with the making of a next-following bobbin.
