Patent number: 6230758Abstract: The sley shaft of a loom, particularly a loom for weaving terry cloth or pile fabric, is rotated so as to provide more time for a gentle beat-up of the weft along the fabric beat-up line. For this purpose, the acceleration of the sley shaft and thus of the reed, which is connected to the sley shaft, toward the beat-up position is first faster to provide more time for the following entrainment of the weft or a group of wefts and for their beat-up by way of a discontinuous deceleration of the sley shaft and reed by a two phase deceleration toward the beat-up line. The two phase deceleration is interrupted by a slower deceleration between the two deceleration phases or by no deceleration between the two deceleration phases. Weft entrainment takes place between the two deceleration phases.Type: GrantFiled: May 30, 2000Date of Patent: May 15, 2001Assignee: Lindauer Dornier Gesellschaft mbHInventors: Valentin Krumm, Stefan Kimmel, Rainer Finger

Patent number: 6112773Abstract: Two different pile heights (a, b) can be selectively formed during the weaving of terry fabric on a loom by shifting the fabric with its actual beat-up line (10a) back and forth relative to a base beat-up line (3). First and second fabric shifting oscillating motions are performed by first and second power or motion transmission couplings (4, 11) driven through eccentric drives (5, 12) from a main loom drive shaft (DS) and controlled through valves by a central loom control (22) in such a way that a second oscillation with a different amplitude is superimposed on a first oscillation between beat-up groups of weft beat-up motions including partial weft beat-ups and a full weft beat-up motion of a reed (2) in the loom. Different oscillation amplitudes cause a beat-up line shift of different length (a or b) whereby different pile heights are formed.Type: GrantFiled: August 12, 1999Date of Patent: September 5, 2000Assignee: Lindauer Dornier Gesellschaft mbHInventor: Erwin Geiger

Patent number: 5590692Abstract: Faults in fabrics such as smooth woven fabrics or pile fabrics caused by transition operational conditions are avoided, especially on air nozzle weaving looms. Such transition operational conditions may occur when rated operating parameters must be changed, for example, due to the use of a different type of weft thread or a change in the weaving pattern and/or weave binding. For this purpose, the weft thread insertion is interrupted only during the duration of the so-called transition operational conditions. Weft insertion is interrupted by performing so-called fluidic or non-fluidic empty or mis-shots. Simultaneously, the warp let-off and the fabric take-up is controlled as a function of the number or duration of the empty or mis-shots in such a way that at this point of time during the transition operating conditions the beat-up edge of the fabric is held in a position away from the beat-up position of the reed.Type: GrantFiled: October 27, 1995Date of Patent: January 7, 1997Assignee: Lindauer Dornier Gesellschaft mbHInventors: Peter D.

Patent number: 5499662Abstract: A method for weaving blemish-free smooth and terry fabric on a loom following a stoppage of the loom after it has woven a fabric fell which terminates in a last weft thread. The loom has a driven reed which reciprocates during normal weaving towards and away from the fell over a predetermined beat-up distance to successively position additional weft threads at predetermined target positions which assure a uniform, blemish-free fabric. Following a loom stoppage, the next weft yarn, for smooth fabric, and a plurality of next weft yarns, for terry fabric, are moved towards the last weft yarn over a compensated beat-up distance which is different from the predetermined beat-up distance to thereby position the next weft yarn at the desired target position relative to the least weft yarn of the fell to avoid the formation of fabric blemishes. Thereafter the reed is again moved over the predetermined beat-up distance during subsequent picks of the loom.Type: GrantFiled: October 12, 1994Date of Patent: March 19, 1996Assignee: Sulzer Rueti AGInventors: Rudolf Vogel, Husnu Evren

Patent number: 5423354Abstract: A drive system for a weaving loom includes at least one four-pivot three-link drive or preferably two such drives for transmitting drive power from a main loom shaft through a cam drive to a slay shaft coupled to the cam drive through the four-pivot three-link drive. The use of two four-pivot three link drives permits operating the weaving loom selectively for producing terry cloth and/or smooth fabric. Each of the four-pivot three-link drives (DL, DR) has four pivots or journals (A, B, C, D) and three links (24, 38, 43; 25, 40, 44). Each four-pivot three-link drive cooperates with a roller carrying cam follower (15) that is controlled by an eccentric cam assembly (7). Both four-pivot three-link drives effectively operate the slay shaft (46) of the loom. A control and engagement mechanism (33, 54) provides for the switching from one four-pivot three-link drive to the other and vice versa, whereby a switch-over from the production of one type of fabric to the other is facilitated.Type: GrantFiled: March 2, 1994Date of Patent: June 13, 1995Assignee: Lindauer Dornier Gesellschaft mbHInventor: Wilhelm Herrlein

Patent number: 5311660Abstract: Disclosed is a method of drilling, desmearing, and additively circuitizing a printed circuit board. The printed circuit board is drilled under conditions which produce glass and polymer smeared vias and through holes. The particulate debris is removed by vapor blasting the drilled printed circuit board. Next the printed circuit board is soaked in a solvent to swell the drill smear on the circuit interplanes of the printed circuit board. This solvent is then removed by entrainment in a gas, and a stream of an aqueous, acidic, oxidizing solution is passed through the printed circuit board holes to remove swollen smear in the thru holes and produce an etchback of conductors. After a water rinse an aqueous reducing solution is passed through the printed circuit board to reduce and remove aqueous acidic oxidizing solution, e.g., residual aqueous acid oxidizing solution. The printed circuit board is rinsed to remove the aqueous reducing solution.Type: GrantFiled: February 10, 1993Date of Patent: May 17, 1994Assignee: International Business Machines CorporationInventors: Warren A.

Patent number: 4569373Abstract: The weaving machine includes an electronic control device which can receive a signal for a reverse-motion of the pile warp let-off drive motor from the card dobby via a sensor when borders (plain woven regions) of the fabric are to be produced within the terrycloth material. When the drive motor briefly runs backward, the tension in the pile warp increases, which causes the plate warp tensioning beam to be shifted into the plain weaving position in which a pivoting lever rides up onto a leaf spring. The latter is shifted into the plain weaving position which causes the increased pile warp tension to be produced. If a terrycloth weaving operation is to be returned to, then the drive motor receives an appropriate signal from the card dobby for a brief fast forward motion of the pile warp beam, which causes a lower pile warp tension to be produced again while the pile warp tensioning beam pivots back into the normal position.Type: GrantFiled: October 17, 1984Date of Patent: February 11, 1986Assignee: Maschinenfabrik Sulzer-Ruti AGInventor: Rudolf Vogel

Patent number: 4566498Abstract: A reed control mechanism for a terry type loom is disclosed. The reed control mechanism enables the reed to perform a three pick cycle comprising partial beat up of the first two picks of weft followed by full beat up of the third pick of weft. Reciprocating motion is applied to a lay beam on which the reed is mounted by a crank arm whose motion is driven by a rotatable driving element. The rotatable driving element is coupled to the crank arm through a mechanical linkage which includes a pneumatic or hydraulic cylinder. The pneumatic or hydraulic cylinder serves to shift the arc of the reed so as to effect partial beat up of certain picks of weft and full beat up of other picks of weft.Type: GrantFiled: September 19, 1984Date of Patent: January 28, 1986Inventors: Gilmer A. Williams, Douglas Burgess
