Patent number: 6047452Abstract: A cylindrical shaped mandrel is used as a support inside the sleeve of tubular knit fabric, for maintaining the cylindrical shape of the fabric during extraction and compacting processes. Encasing the fabric and the mandrel is a larger diameter cylindrical ring member which presses the fabric against the mandrel in order to perform the extraction and compaction processes. The ring member extends for some distance in the longitudinal direction of travel of the knit fabric and contains a mechanism, such as a detent, for retaining the mandrel in place. A rope of tubular fabric is conveyed into the mandrel/ring assembly by an endless conveyor or belt made from a flexible material such as rubber. As the fabric is fed onto the mandrel, the belt forms a cylindrical sleeve around the fabric and the mandrel and is compressed by the cylindrical ring.Type: GrantFiled: December 10, 1998Date of Patent: April 11, 2000Inventor: Frank Caruso

Patent number: 6041482Abstract: A tubular knit fabric descending from a knitting head is spread and flattened by a fabric spreader disposed within the fabric just above a pair of take-down rolls forming a nip through which the fabric passes. The spreader comprises a generally flat frame formed by tubular members. The tubular members include a pair of U-shaped sections having open ends spaced apart and facing each other, and having closed ends defining opposite fabric-engaging edge surfaces of the frame. First legs of the U-shaped sections are telescopingly and adjustably joined to a tubular center section, the center section and first legs collectively forming a roll-engaging member for pressing the fabric against the take-down rolls. The width of the spreader is adjusted by releasing screws fixing the center section to the U-shaped sections, sliding the U-shaped sections inward or outward, and using the screws to fix the frame at the new width.Type: GrantFiled: May 28, 1999Date of Patent: March 28, 2000Assignee: Mayer IndustriesInventors: Xuejian Zhu, Aiken Anderson Still, IV

Patent number: 5884377Abstract: A mangle for circular knitted fabric has a circular spreader is combined with several mangling stations circularly arranged around the spreader for the removal of treatment liquor from tubular fabrics. In order to protect the fabric against excessive squeezing, an upper roller head is entirely avoided by confining the circular spreader in the horizontal direction exclusively by the mangling stations. The vertical support of the spreader is provided fully by the mangling stations if the mangling rollers are mounted in positions slanting to the vertical. If the mangling rollers are not mounted in slanted positions it is preferred that a lower roller head operated by a lifting mechanism assists the mangling rollers in supporting the spreader (8) vertically. In both instances an upper roller head becomes unnecessary.Type: GrantFiled: January 20, 1998Date of Patent: March 23, 1999Assignee: Lindauer Dornier Gesellschaft mbHInventors: Andreas Rutz, Werner Strudel

Patent number: 5233734Abstract: Circular spreaders for tubular textile goods make it necessary to keep the spreader arms in a desired spread-out condition so that an unintended reduction in the diameter of the circular spreader is prevented. Such unintended reduction could be caused by operational vibrations or by impacts to which the spreader may be exposed during operation. For this purpose the spreader is equipped with a locking mechanism which, on the one hand, permits a continuous adjustment or a stepwise adjustment of the circular spreader to a maximum spread diameter and which, on the other hand, prevents a reduction of the once adjusted spreader diameter. A ratchet mechanism is provided for this purpose.Type: GrantFiled: March 13, 1992Date of Patent: August 10, 1993Assignee: Lindauer Dornier Gesellschaft m.b.H.Inventors: Werner Strudel, Walter Miotke

Patent number: 5077873Abstract: Tubular fabric that is being expanded radially outwardly by a so-called circular expander, has a tendency to develop a reduced pressure inside the volume of the tubular fabric, whereby the operation of the expander is hindered. To avoid the formation of reduced pressure, the expander is equipped with at least one air blower nozzle for introducing pressurized air into the space enclosed by the tubular fabric. The air blower nozzle is movable toward and away from the tubular fabric and preferably can stretch the fabric slightly to improve the passage of air through the fabric, which is sufficient permeable to pressurized air.Type: GrantFiled: August 30, 1990Date of Patent: January 7, 1992Assignee: Lindauer Dornier Gesellschaft m.b.H.Inventor: Werner Strudel

Patent number: 4885826Abstract: A spreader for tubular fabric has a divided central carrier to which struts or support arms are pivoted for carrying longitudinal guide rods, e.g., in parallelogram type fashion. The two sections of the central spreader carrier telescope relative to each other against the force of a spring which presses the two sections of the spreader against upper and lower sets of position determining roller pairs. Support rollers are inserted between the positioning determining roller sets at the upper and lower ends of the spreader. The operation or action of the struts or support arms enables the adjustment of the spreader even in its working position while fabric is running over the spreader. This is possible by changing the axial length of the spreader by an externally arranged lifting mehcanism for raising and lowering at least one of the position determining roller sets. Raising one roller set decreases the spreader diameter while lowering at least one roller set increases the spreader diameter.Type: GrantFiled: September 29, 1988Date of Patent: December 12, 1989Assignee: Lindauer Dornier Gesellschaft mbHInventor: Werner Strudel

Patent number: 4843669Abstract: The invention relates to the wet processing in particular of knitted tubular material in the broad tubular state which in a first processing section is led through a fluid bath then inflated to form a balloon section and afterwards led in the broad tubular state through the gap between a pair of squeezer rollers. Within the fluid bath the incoming material in hank form is subjected to twist sensing and if any twist is detected the incoming tubular material is rotated in the region before the first processing section to undo the twist. The completely and stably relaxed and untwisted tubular material leaves this first processing section in a stable broad tubular state and can then be passed in an optimum manner through the succeeding principal processing sections.Type: GrantFiled: October 9, 1987Date of Patent: July 4, 1989Assignee: Bruckner Apparatebau GmbHInventors: Werner Koch, Manfred Schuierer

Patent number: 4835992Abstract: The invention relates to a method and apparatus for the treatment of continuously moving tubular fabric (1) in the wet state, in which this tubular fabric is deliberately expanded in an expansion zone (3) by blowing air in and the fabric width (WB) effectively obtained is measured. The actual value obtained for the fabric width is compared with a predetermined theoretical value and in the event that they differ a correction value is formed and the quantity of air blown into the tubular fabric is controlled as a function of this correction value. The tubular fabric (1) is expanded immediately after wet treatment and is then delivered to the expansion zone free of tension and with a sealing material store. In this way a compact apparatus is achieved which functions simply and reliably.Type: GrantFiled: July 10, 1987Date of Patent: June 6, 1989Assignee: Bruckner Apparatebau GmbHInventor: Werner Koch
