Patent number: 6609278Abstract: The invention relates to a pin assembly which keeps single-piece, two-piece or multi-pieced yarn processing elements, especially yarn interlacing spinnerets or thermal treatment elements, in an exact position during an entire service life, despite the extreme effects of preparations used. Instead of a traditional soldered joint or an adhesive connection, mechanical clamping means are used to fix the dowel pins to one part of the spinneret. Fixation of the dowel pins is not affected by heat or chemical preparations. The clamping means consists of a simple clamping ring holding the dowel pin in position directly inside the body of the spinneret between the clamping pin and an after-body. The novel positioning solution can be used with individual parts of spinnerets, parts of spinnerets in machines or multiple parts of spinnerets. The dowel pins enable the entire spinneret to be substantially miniaturized and allow narrow separation between various yarn runs, which was previously impossible.Type: GrantFiled: November 17, 2000Date of Patent: August 26, 2003Assignee: Heberlein Fibertechnology, Inc.Inventors: Helmut Ritter, Patrick Buchmüller, Gotthilf Bertsch, Erwin Schwarz

Patent number: 6148490Abstract: A texturizing device for yarn texturing includes a yarn channel having movable components for rapidly releasing the entire yarn path. The nozzle body of the texturizing device preferably includes two parts as a glide plate and a sliding nozzle plate, in which the yarn channel is arranged in a U-shape in the slide plate and moved in relation to a flat glide plate via an articulated lever. Depending on the position of the articulated lever, the entire yarn path is fully open for threading or closed for texturing operation. A deflector may also be provided and can either be connected to moving parts or non-moving parts of the device. An air supply may be coupled with the sliding nozzle plate such that the air supply is blocked in the threading position of the articulating lever and open in the operating position of the articulating lever.Type: GrantFiled: October 14, 1998Date of Patent: November 21, 2000Assignee: Heberlein Fibertechnology, Inc.Inventor: Gotthilf Bertsch

Patent number: 6088892Abstract: A method of air jet texturing is described wherein the intensity of texturing is proposed to be increased in that an air flow exceeding Mach 2 is obtained by the design of the nozzle duct. The total opening angle of the nozzle duct (11) directly in front of the texturing zone is designed to be greater than the ideal Laval angle with an effective length which is preferably a multiple of the smallest diameter of the nozzle. This predominantly improves the quality of texturing, quite particularly at higher production rates. These can be increased into the range of 600 to 1000 m/min and higher. It has surprisingly been found that the novel nozzle core (10) can be designed so that it has all advantages of the novel invention and can be used as a substitute for prior art nozzle cores. The same applies to the complete texturing head as the novel invention can be used within the same geometric external dimensions, the same air pressure and the same quantity of air.Type: GrantFiled: February 25, 1998Date of Patent: July 18, 2000Assignee: Heberlein Fibertechnology, Inc.Inventors: Gotthilf Bertsch, Erwin Schwarz

Patent number: 5640745Abstract: An apparatus and method for the manufacture of a mixed yarn consisting of two components, continuous filament yarn and staple fibers. The mixed yarn is manufactured by an air jet texturing process. It has been possible to bind the staple fibers undisplaceably into the yarn, and this is ensured by the loops on the continuous filaments produced during texturing. Owing to the formation of a suction zone of the airstream directly before the beginning of actual texturing, the staple fibers can be sucked in and can be blended into the interior of the yarn and can be secured firmly in the yarn by the loops. The invention relates to a new method of manufacture and to an apparatus, or an entire machine, with which the known loop yarn or the new mixed yarn can now be manufactured selectively.Type: GrantFiled: January 26, 1996Date of Patent: June 24, 1997Assignee: Heberlein Maschinenfabrik AGInventors: Gotthilf Bertsch, Erwin Schwarz, Albert Rebsamen

Patent number: 5316050Abstract: In a selvage laying equipment a catcher nozzle (44) with a catcher channel (45) lying in axial prolongation of the nozzle and a threader nozzle (41) with a catcher channel (42) lying in axial prolongation of the nozzle are arranged in a carrier (54) with the axes of their air jets crossing one another, which enables a narrow construction of the device for threading the end (21a) of the weft yarn into the eye or hook of the selvage laying needle (11) and hence short ends (21a) to the weft yarn and narrow selvages, respectively. Bits of dirt such as fluff are reliably carried away from the gap (55) in the carrier (54) as well as from the catcher channels (42, 45) and the formation of an air dam is prevented.Type: GrantFiled: March 23, 1993Date of Patent: May 31, 1994Assignee: Gebrueder Sulzer AktiengesellschaftInventor: Gotthilf Bertsch

Patent number: 5080143Abstract: A pneumatic selvedging device for a loom has a weft yarn end temporarily retained by a threading nozzle. A tuck-in needle takes over the retained weft yarn end for drawing in between the warp yarns of a loom. The threading nozzle is mounted on a retaining arm which is pivotally mounted on a shaft disposed within a casing above the cloth and near the beating-up edge for the weft yarn. A second drive shaft is mounted in the same casing transverse to the shaft for the retaining arm for driving the tuck-in needle. The shaft for the tuck-in needle and the shaft for the threading nozzle are driven off a common drive shaft via cams and cam follow-up levers. A shears may also be mounted on the retaining arm and be actuated by a link pivotally connected between a pivotal blade of the shears and the casing.Type: GrantFiled: January 22, 1991Date of Patent: January 14, 1992Assignee: Sulzer Brothers LimitedInventor: Gotthilf Bertsch

Patent number: 4984608Abstract: A selvedge-forming device has a tuck-in needle having, at least in the end part introducible into the shed, a wedge shaped cross-section. The needle also has an elongate yarn entry aperture whose major dimension extends in the direction of the length of the end part of the needle. The end part also has an end face which leads in the direction of entry into the shed and which co-operates with the long side near the reed to form a tip pointing away from the shed apex. The needle can make pivoting movements out of the shed very close to the shed apex so that the weft yarn end is tucked in correspondingly close to the shed apex. Because of the elongate shape of the aperture the weft yarn end can be bent readily and can therefore be threaded into the aperture with a reduced blowing pressure of a threading nozzle.Type: GrantFiled: July 14, 1989Date of Patent: January 15, 1991Assignee: Sulzer Brothers LimitedInventors: Gotthilf Bertsch, Josef Braum

Patent number: 4565225Abstract: A blower nozzle is provided on the shot or weft insertion side of the weaving machine for blowing the severed end of the weft thread into an eyelet of a selvedge-tucking needle. By transferring the weft thread end by means of the blower nozzle, a particularly short time within the operating cycle of the weaving machine is required for the procedure of transferring the weft thread end to the selvedge-tucking needle. This permits higher operating speeds of the weaving machine.Type: GrantFiled: August 20, 1984Date of Patent: January 21, 1986Assignee: Maschinenfabrik Sulzer-Ruti AGInventor: Gotthilf Bertsch

Patent number: 4552187Abstract: A retention nozzle is provided at the catch side of the weaving machine for clamping or retaining the weft thread end during severance of the weft thread by means of a shear. A transfer nozzle is also provided at the catch side. When the weft thread lies over the transfer nozzle after being severed, the transfer nozzle is supplied with blower air and subsequently the supply of blower air to the retention nozzle is interrupted. In this manner the weft thread end is withdrawn from a catch channel of the retention nozzle and blown into a catch channel of the transfer nozzle. During this operation, the weft thread end is conducted through an eyelet of a selvedge-laying needle and thereby transferred to the latter. The retention nozzle permits severance of the weft thread by means of the shear even before the weft thread is in alignment with the eyelet of the selvedge-laying needle and the transfer nozzle.Type: GrantFiled: January 14, 1985Date of Patent: November 12, 1985Assignee: Maschinenfabrik Sulzer-Ruti AGInventors: Gotthilf Bertsch, Josef Braun
