A creel for directly supplying twisted yarns to a machine (13) such as a loom or warper from a plurality of yarn bobbins (3) arranged on a creel (1) for holding non-twisted yarn (2). Two banks of bobbins (3), optionally contrarotate at a predetermined speed to respectively provide "S-twisted" and "Z-twisted" yarn streams (4) having a desired twist number. The bobbins (3) are disposed on a plurality of spindles (5) that are driven by suitable drives (6). A bobbin attachment (7) is mounted at a free end of each bobbin (3) and fixedly supported on the spindle (5). A yarn storage (8) is provided on the attachment (7) and includes a yarn adjustment ring (9) for providing yarn delivery in a stable manner under appropriate tension. Once the yarn has passed the yarn storage (8) and yarn adjustment ring (9), a desired twist is imparted to the yarn (2), and twisted yarn (4) is delivered to the machine (13).
A creel for supplying twist yarns arranged parallel to each other to a predetermined machine, said twist yarns being prepared by withdrawing a non-twist yarn from one of multiple bobbins arranged on the creel and twisting the non-twist yarn midway of a supply passage to the predetermined machine, said creel comprising a plurality of spindles, each fixedly supporting the respective bobbin, and at least one means for driving the spindles in an optional rotational direction and at an optional rotational speed, and an attachment having a yarn storage, said attachment being mounted at a tip end of the bobbin supported on the spindle and said yarn storage having a yarn adjustment ring fitted thereon, wherein after the non-twist yarn withdrawn from the bobbin passes the yarn storage and the yarn adjustment ring while being directed to the predetermined machine, a twist is imparted to the non-twist yarn to obtain a twist yarn.
A creel, comprising a plurality of spindles, each fixedly supporting a bobbin on which a non-twist yarn is wound so that the bobbin is rotatable together with the spindle and at least one means for driving spindles, in which a twist is imparted to the non-twist yarn while the non-twist yarn is withdrawn from the bobbin and supplied to a predetermined machine, wherein each of the spindles is a single spindle having at least two bearings in a middle portion thereof as seen from a front side and extending rightward and leftward to form holders for fixedly supporting the bobbins, and said plurality of the spindles are arranged to form multiple horizontal rows positioned in a multistage manner in the vertical direction as seen from a lateral side;
