Publication number: 20050236062Abstract: The invention relates to a method for the taut-holding of the weft thread (15) in the mixing tube (4) of the main nozzle (1) of an air jet loom, and an air jet loom for the carrying out of the method. The invention has the underlying technical object of avoiding an air stream effective over nearly the total length of the main nozzle (1) and disadvantageously influencing the structure of the weft thread (5) during its idle phase in the main nozzle (1), and nonetheless holding the weft thread (5) taut in the main nozzle (1). This is achieved in that the air stream, during the idle phase of the weft thread (5), impinges on only its front end (5a) in the mixing tube of the main nozzle.Type: ApplicationFiled: May 6, 2003Publication date: October 27, 2005Inventors: Peter Dornier, Adnan Wahhoud

Patent number: 5082029Abstract: A loom for fabrics which are sensitive to loom stopping marks, especially twill fabrics, has a disengagement lever (14) on an eccentric drive mechanism of the loom. The disengagement lever is operated by a controlled driving device, so that it causes all heald frames or shafts of the loom to assume a central shed position when the loom is stopped. Thus, stoppage marks in the fabric are avoided since the heald frames no longer stretch the warp threads during a loom stoppage since the frames are moved to a closed shed position during stoppage.Type: GrantFiled: October 5, 1990Date of Patent: January 21, 1992Assignee: Lindauer Dornier Gesellschaft mbHInventor: Peter Dornier

Patent number: 4919171Abstract: An air jet weaving loom equipped with a rod-type expander, has a weaving reed forming a weft thread insertion channel. The expander has an extension reaching toward the channel and preferably to about the center of the channel. The extension has a top surface which forms an elongation of a fabric supporting surface of the expander. This arrangement assures that the beat-up or interlacing point is always located about centrally in the weft thread insertion channel.Type: GrantFiled: April 7, 1989Date of Patent: April 24, 1990Assignee: Lindauer Dornier Gesellschaft mbHInventor: Peter Dornier

Patent number: 4815181Abstract: In a film stretching machine having tentering chains travelling in an endless loop, the forward advance tracks of the tentering chains are laterally adjustably arranged within the machine housing for adjusting to fit different material web widths and for adjusting the lateral or widthwise stretching ratio. The tentering chain reversal guide arrangements at the inlet and outlet ends of the machine are correspondingly laterally slidably adjustable. The return tracks for the tentering chains are arranged outside of the housing in a fixed position and orientation relative to the housing. Straight transition guide portions pivotally connect the stationary return chain tracks to connection points of the respective laterally movable reversal guide arrangement. The straight transition guide portions are each articulated at one end to the respective return chain track and at the other end to the respective reversal guide arrangement. The return chain tracks may be either open or completely closed channels.Type: GrantFiled: February 3, 1988Date of Patent: March 28, 1989Assignee: Lindauer Dornier Gesellschaft mbHInventors: Peter Dornier, Rudolf Langer, Hans-Jurgen Maierhofer

Patent number: 4655263Abstract: A shuttleless loom is equipped with a displacement device for the control member or rail of the clamping device of the gripper, whereby the control rail can be displaced in parallel to the thread inserting motion of the gripper. This displacement of the control rail permits the proper presentation and transfer of the weft threads into the clamping device of the gripper even if the weft thread fan contains a substantial number of weft threads. This control rail displacement in the direction of the thread insertion into the loom shed takes place at each picking or inserting movement of the gripper and is substantially synchronous with the gripper motion after a thread transfer. When the number of threads in the thread fan is relatively small, the displacement device can be switched off.Type: GrantFiled: March 21, 1986Date of Patent: April 7, 1987Assignee: Lindauer Dornier Gesellschaft mbHInventors: Peter Dornier, Valentin Krumm

Patent number: 4608767Abstract: Three consecutive work zones are provided in a drying apparatus for tubular textile wares, equipped with an expander arranged vertically floating in the interior of the tubular textile material. Zones, in which drying air is blown from the outside into the tube interior, are located upstream an entry ring which expands the tube and downstream of a corresponding exit ring of the expander, which may be circular, for example. In a third, center zone located between the entry ring and the exit ring of the expander, the tubular textile material is exposed to substantially radially outwardly directed suction of the drying air which may cause undesirable deformation of the tubular textile material. A gas-permeable substantially cylindrical jacket is provided in the center zone. This jacket envelopes the tubular textile material which bears against the inner wall of the jacket during the drying, whereby such deformations are avoided or controlled.Type: GrantFiled: May 7, 1984Date of Patent: September 2, 1986Assignee: Lindauer Dornier Gesellschaft mbHInventor: Peter Dornier

Patent number: 4546803Abstract: This system is intended for relieving the drives of weaving machine components alternatingly rocking between two end positions, for instance a first rocking member forming a gripper rod drive and a second rocking member forming a reed drive. A common energy storing device, for instance a spring, is connected with the two separate drive units, so that each end of the spring is connected to one of the two separate rocking members. The rocking motions of the two rocking drive members do not overlap in time.Type: GrantFiled: September 7, 1983Date of Patent: October 15, 1985Assignee: Lindauer Dornier Gesellschaft mbHInventor: Peter Dornier
