The invention relates to a winding device for winding strand-like material to be wound onto a rotating reel (2), which winding device has a laying apparatus (9) by means of which the material to be wound is guided to the run-on point on the winding. The laying apparatus (9) is substantially movable in the direction of the axis of rotation (3) of the reel (2). Furthermore the winding device (1) has at least one sensor for determining the run-on angle of the material to be wound onto the winding. The winding device (1) is designed in such a way that the movement of the laying apparatus (9) during the winding process is regulated as a function of the run-on angle determined by means of the at least one sensor. According to the invention the distance between the run-off point at which the material to be wound leaves the laying apparatus (9) and the run-on point during the winding process at least at times is at most four times, preferably at most twice, more preferably at most equal to the diameter of the material to be wound. Due to this small distance, a good winding of the reel is achieved, in which the individual turns rest against one another. In particular the “crossing over” of individual turns is avoided and the material to be wound is treated carefully.

A leasing device including at least one first part connected to a frame element of a reeler and at least one second part including a mechanism for depositing and guiding at least one thread. The first part and the second part are connected to one another such that the second part occupies a first working position, in which the thread can be deposited in the form of a reel, and a second position, in which the second part is separated from the first part, corresponding to a maintenance phase of the second part.

A coil winding apparatus 1 includes a transvers mechanism which displaces a wire supply part 8 and a spinds 5 to which a bobbin 4 is fitted relative to each other in an axial direction. This traverse mechanism includes a first traverse mechanism 11 and a second traverse mechanism 15 which have a different displacement range and displacement pitch. The first traverse mechanism 11 and second traversemechanism 15 are displaced independently of one another, so even when a wire of fine diameter is rapidly wound on a narrow width, the coil winding alignment does not break down, and the coil turns can be wound at high speed in an orderly arrangement.

A winding machine (1) includes a yarn traversing apparatus (2) including a housing (3) having an elongated opening (11). A reversing screw thread shaft (5) has an outer surface (14), it is rotatably supported in the housing (3) and it includes en endless screw thread groove (4). A traversing yarn guide (6) includes a body (7), a shuttle (8) being designed and arranged to engage the endless screw thread groove (4), a yarn guide (9) and a guide bush (12) having an inner surface (13). The traversing yarn guide (6) is designed and arranged to be driven by the reversing screw thread shaft (4) to reciprocate in an axial direction. The yarn guide (9) is designed and arranged to project out of the elongated opening (11) of the housing (3). The inner surface (13) of the guide bush (12) is designed and arranged to at least partially surround the outer surface (14) of the reversing screw thread shaft (5).

A method of inserting a fill yarn on an air jet loom includes propelling a fill yarn with one or more air jets from the insertion side to the exit side of the loom, where the yarn comprises a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape, and where the flat spots provide increased drag for propulsion by the air jets.

A replaceable traverse module for a winder for winding endless filaments comprises a housing resting on a support element provided in the machine. The housing and the element have interengaging parts to form a guide for the module during insertion onto the machine, and which also cooperate to hold the module in a predetermined position relative to the threadline.

An apparatus for winding a textile yarn into a cross-wound package is disclosed, in which the yarn is wound about the package at a substantially constant rate while the yarn is guided onto the package by a traversing guide. The apparatus includes a yarn guide means which is reciprocated along a linear stroke path, and means are provided for recovering the kinetic energy of the yarn guide means during its reversal of movement at each end of the stroke path. Several specific embodiments of the yarn traversing guide are disclosed, and in one embodiment the traversing guide includes gripper means mounted on a slide which is positioned between parallel runs of a drive belt, and control means for moving the gripper means to alternately engage the two runs of the belt and thus reciprocate the slide.

An apparatus, method and package are provided for producing and winding strands to achieve good split efficiency on removal of the plurality of strands from the package for further processing and to produce a package of wound strands having good edges.The apparatus has a fiber forming means, an applicating means for applying chemical treating compositions to the fibers, gathering means to gather the fibers into a plurality of strands, a rotatable winder to attenuate and wind the strands, a slotted traversing guide, a reciprocating means, and contact means at each end of the reciprocating stroke of the traversing guide. The slotted traversing guide has more than one slot where the terminal portions of the slots have curved ends to retain a strand and are located directly behind the terminal portion of the preceeding slot. The slotted traversing guide deposits the strands on the rotating winder and as the traversing guide approaches the point at which it reverses to traverse in the opposite direction parallel to the axis of rotation of the winder the strands above or below the traversing guide contact a contacting means to restrain the traversing movement of the contacted segment of the strands to apply tension to the strands being wound onto the winder. This additional tension assists in producing squarer edged packages having good split efficiency.
