Patent number: 4972326Abstract: Apparatus and a method records a flaw in a fabric web during a flaw inspection. The flaw is recorded by a mark placed on the fabric web along with the X- and Y-values of a system of points defining a boundary line around the flaw. The mark and a side edge of the fabric web, respectively, serve as reference points for these X-and Y-values.Type: GrantFiled: January 25, 1990Date of Patent: November 20, 1990Assignee: Krauss u.

Patent number: 4874157Abstract: In order to improve a method for minimizing material utilization during spreading of a flawed material web, in particular, a fabric web, such that it can be carried out in a manner which always economizes on material or fabric, it is proposed that proceeding from a region determined by the flaw, a set of at least two virtual stop lines be placed in the pattern representation and all flawless pattern pieces cut by the virtual stop lines be determined, that by applying an optimization criterion which takes into consideration the flawless pattern pieces cut by the virtual stop lines and the flawed pattern pieces, one of the virtual stop lines be selected and the stop line be arranged at it, that a maximum distance from the stop line be determined which maximum distance corresponds to the furthest distance of a start of one of the flawless pattern pieces cut by the stop line or of one of the flawed pattern pieces from the stop line, and that the restart line be placed in the direction opposite to the spreading diType: GrantFiled: April 12, 1988Date of Patent: October 17, 1989Assignee: Krauss u.

Patent number: 4617737Abstract: A machine for cutting out flat material comprising a support for the flat material, a carriage guided for displacement along the support by at least one guide rail, the carriage bearing a beam extending above the support and pivotable, in relation to the carriage, about an at least approximately vertical, first pivot axis, this beam having at least two arms interconnected by a joint having a second pivot axis parallel to the first pivot axis and the outer arm of said two arms bearing a cutting mechanism pivotable, in relation to the outer beam arm, about a third pivot axis parallel to the first pivot axis and a foot of the cutting mechanism being in contact with the support during operation. In order to simplify the construction of the beam but still ensure that the cutting mechanism always rests perpendicularly on the support, this cutting mechanism is adapted to swivel, in relation to the support, about a tilt axis parallel to the support and rests with its foot on this support.Type: GrantFiled: March 29, 1985Date of Patent: October 21, 1986Assignee: Krauss u. Reichert GmbH & Co. KGInventor: Rolf Jung

Patent number: 4575065Abstract: A web laying machine has a laying carriage driven back-and-forth over the laying table in a web laying direction. The laying carriage includes a chassis, an upper part mounted on the chassis and movable transversely to the laying direction relative to the chassis and rotatable about a vertical axis. A sled, carrying a support mechanism for a web supply reel is arranged on the upper part, and has a first position and a second position spaced from the first position in a direction parallel to the laying direction. The sled is movable from the one to the other position by rotating the upper part through an angle of 180.degree. or by linearly displacing the sled relative to the upper part.Type: GrantFiled: April 8, 1985Date of Patent: March 11, 1986Assignee: Krauss u. Reichert GmbH & Co. KG, SpezialmaschinenfabrikInventors: Rolf Jung, Winfried Buchmann, Albert Buss

Patent number: 4557051Abstract: The invention relates to a cutting machine, in particular a fabric cutting machine, comprising a bearing table for the material and a supporting structure, which is displaceable along the table, for a cutting tool rotatable about a vertical axis and comprising drive means for driving the cutting tool relative to the table. In the case of a cutting machine of this type the invention has a first angular position detector associated with the cutting tool, this first angular position detector generating signals corresponding to the angular position of the cutting tool. In addition, a guide handle is provided on the cutting tool, this handle having associated signal generating means for producing additional control signals such that, on the basis of the signals from the first angular position detector and the additional signal generating means, control signals may be generated for the drive means of the cutting tool, which enable the cutting procedure to be servo-assisted when the cutting tool is guided by hand.Type: GrantFiled: October 27, 1983Date of Patent: December 10, 1985Assignee: Krauss u. Reichert GmbH & Co. KGInventor: Rolf Jung

Patent number: 4457505Abstract: A web laying machine for laying a web in superposed layers on a laying table has a laying carriage traveling back and forth along the length of the laying table between first and second end position, a web laying unit vertically displaceably mounted on the laying carriage and a web holding unit arranged at the first end position for immobilizing the web while the laying carriage moves from the first end position to the second end position. The web laying unit is maintained, during at least the greatest part of the travel of the laying carriage between the two end positions, at a laying height above the laying table. The laying height is at a higher level than the height position of the web laying unit while the laying carriage is in the first end position. Further, the web laying unit is lowered at least approximately to the level of the precedingly deposited web layer or, in the absence thereof, to the level of the laying table, at the latest when the laying carriage reaches the web holding unit.Type: GrantFiled: September 30, 1982Date of Patent: July 3, 1984Assignee: Krauss u.

Patent number: 4107839Abstract: A manually guided cutting machine for cutting stacked layers of cloth and the like which includes a frame having a downwardly extending column with a foot plate of flat extensive construction for supporting the machine on a cutting table as the machine is manually guided. A reciprocated knife blade at the front edge of the column, driven by an air motor on the frame, cuts into the material supported upon the foot plate. Exhaust air from the motor is conducted to a centrally located confined recess under the foot plate free of any communication with the top of the plate so that the foot plate floats on a cushion of air and with the noise of the exhaust air being muffled by the foot plate and the overlying material.Type: GrantFiled: May 6, 1977Date of Patent: August 22, 1978Assignee: Krauss u.

Patent number: 4092777Abstract: A cutting-out machine for flat material such as cloth has a slit blade cutting mechanism mounted on one end of a double-arm beam. The beam arms are pivotally connected to one another about a vertical axis. The cutting mechanism is pivotally connected to one end of the beam, preferably in an adjustable spring-loaded mount. The pivot axis is vertical and aligned with the cutting edge of the slit blade. The other end of the beam is pivotally connected, also along a vertical axis, to a carriage that rides on guide tracks extending along a longitudinal edge of a support table for the material. The carriage is preferably driven by an electric motor under the control of a switch located on the cutting mechanism. The beams arms are substantially equal to the width of the support table when the beam is fully extended.Type: GrantFiled: March 10, 1977Date of Patent: June 6, 1978Assignee: Krauss u.
