Adjustable heating apparatus for an advancing yarn

Heating apparatus for an advancing yarn

A yarn false twist crimping machine which comprises a processing frame which mounts the yarn processing components, a creel for mounting the yarn packages, and a take-up frame which is laterally spaced from the processing frame on the side thereof opposite the creel so as to define an operator aisle therebetween. An elongate heater is mounted to the take-up frame and an elongate cooling plate is mounted to the processing frame, and a false twist unit is mounted to the processing frame below the outlet end of the cooling plate. The yarn is guided from the creel in a generally planar arrangement across the operator aisle and to a first yarn feed system which is mounted on the take-up frame. The yarn then advances through the heater and cooling plate to the false twist unit and so as to loop back through the plane defined by the yarns being fed from the creel. Two such machines may be mounted in a mirror image relationship so as to define a service aisle which is bordered by the take-up frames of the two machines, thereby providing for the efficient servicing of the take-up devices of the two machines.

Yarn false twist crimping apparatus

Heater for an advancing yarn

A yarn winding apparatus for winding a cross wound package, and comprising a cutting blade arranged below the traversing triangle and a yarn lifting member which is adapted for movement between positions below and above the traversing triangle. When the winding of a package is completed, the lifting member is lifted, which in turn lifts the advancing yarn from its traversing triangle, and in addition, the lifting member captures and retains the advancing yarn in a laterally fixed position. Upon the subsequent lowering of the lifting member, the captured yarn is brought into the engagement with the cutting blade and severed. In the lifted position of the lifting member, the advancing yarn also may be lifted from its reciprocating yarn guide so that a plurality of circumferential final winds are formed on the completed package.

Yarn winding apparatus with yarn cutting capability

A yarn heating apparatus which is adapted for use in a yarn false twisting machine. The heating apparatus includes an elongate heating surface, and a plurality of yarn guide members mounted in a longitudinally spaced-apart arrangement along the length of the heating surface, for guiding an advancing yarn therealong in a laterally zigzagged path of travel which is adjacent but spaced from the heating surface.

False twist roll

An apparatus and method for processing a warp sheet of synthetic multifilament yarns is disclosed, and wherein the yarns may be withdrawn from supply packages and advanced along a path of travel in warp sheet form, heated and drawn while in advancing warp sheet form to orient the filaments, and then wound for example on a warp beam. Upon detection of a yarn break, the advance of the warp sheet is terminated, and means are provided for interrupting the application of heat to the sheet while the advance is terminated so as to avoid damage to the remaining yarns from a continued application of heat.

Method for processing a warp sheet of yarns

A yarn conveying apparatus is disclosed, and which comprises a pair of circular discs, each having a yarn engaging front surface. The discs are mounted for rotation about respective axes which are inclined with respect to each other, and such that portions of the respective yarn engaging front surfaces are disposed in a closely adjacent opposing face-to-face relationship and define a yarn advancing zone therebetween. The discs are resiliently biased toward each other at the yarn advancing zone, and so that the discs are adapted to engage and advance a yarn which is guided through the advancing zone, without substantial slippage.

Yarn conveying apparatus

A yarn heating apparatus and method is disclosed which is adapted for the continuous heat treatment of a running synthetic yarn in a yarn false twist texturizing machine or the like. The apparatus includes a yarn guide tube through which the running yarn is conducted, and a surrounding heater box is provided for heating the exterior of the yarn guide tube so as to heat the running yarn as it is conducted therethrough. Also, air supply means is provided for positively introducing outside ambient air into the yarn guide tube adjacent the entry end thereof, and such that turbulence is produced in the air as it moves through the yarn guide tube to thereby improve heat transfer between the tube and the running yarn.

Yarn heating apparatus and method

An apparatus is disclosed for simultaneously air jet entangling a plurality of advancing multifilament yarns. The apparatus includes a plurality of elongate air jet beams, with each beam having a longitudinal air passageway extending along its length, and at least one row of closely spaced air jet nozzle heads supported along each of the beams. Each of the nozzle heads includes a plurality of individual yarn entanglement nozzles and a central air chamber connecting the central air chamber to the air passageway. Also, an air jet aperture communicates between the air passageway and the yarn duct of each entanglement nozzle for directing an impinging airstream against an advancing yarn passing through the duct. The beams are mounted for adjustment on a supporting frame so that the nozzle heads may be positioned in proper alignment with a sheet of yarns passing therethrough. The beams may be rectangular or round in cross section and the nozzle heads are releasably connected along the length of the beams. An enclosure suction box surrounds the beams and removes the air exhausted from the entanglement jets and acts to insulate the noise of the entanglement jets.

Apparatus for air entangling a plurality of advancing yarns

A yarn heating chamber is disclosed which comprises a rigid outer housing of U-shaped cross section and including transversely spaced apart side walls, and three plates mounted between the two side walls. A contact pressure gap is formed between the side walls and the adjacent surfaces of the two outer plates, and the central plate includes a yarn receiving groove on each of its outer surfaces. The central plate is laterally movable to a threading position wherein the grooves are exposed, and heating duct means is provided for introducing a hot pressurized vapor into the contact pressure gaps, to bias the two outer plates inwardly toward each other and thereby resiliently engage the central plate therebetween. The pressurized vapor is also conducted to each of the yarn receiving grooves.

Upon detection of a yarn break, the advance of the warp sheet is terminated, and means are provided for interrupting the application of heat to the sheet while the advance is terminated so as to avoid damage to the remaining yarns from a continued application of heat.
