Abstract: A method and system of cutting parts from sheet material is disclosed. The system identifies critical segments of the cutting path where cutting difficulties may arise and modifies the data that guide the cutting tool for more accurate cutting through the critical segments. In particular, the system identifies segments of the cutting path proximately close to one another called “common line segments” and generates a optimized cutting path using a single pass to cut common line segments and minimizing total cutting time, including dry haul time. The method and system of the present invention provide an optimal cutting path and control of a cutting tool resulting in higher quality cut pieces and the higher throughput. Therefore, the method disclosed allows for and makes desirable the close nesting of templates without buffers.

Abstract: In a method for compensating for pattern distortion of sheet-type work material spread onto a support surface a processing apparatus is provided and carries said support surface. The work material is spread onto the support surface and images of selected areal portions of the work material are captured. A controller analyzes these images and projects them onto a display whereupon the images are mapped to define any distortion in the work material. The controller then undistorts the images of these areal portions and projects them back onto the display so that an operator can position undistorted digital representations of pattern pieces onto the undistorted images of the work material. The controller then distorts the geometry of the pattern pieces positioned on the work material by the operator to conform to the distortion in the spread material.

Abstract: An improved method and apparatus for cutting graphics areas from a sheet of material bearing a combination of graphics areas and a plurality of registration marks in predetermined positions with respect thereto, the combination being in a predetermined approximate position and orientation with respect to a set of reference features of the sheet. The method involves automatically determining whether the reference features are in an expected coordinate region on a sheet-receiving surface, and, if not, automatically determining the coordinate region of such features. Further steps then include sensing metrics of the reference features to determine the position and orientation of the sheet, inferring therefrom the approximate positions of the registration marks and then sensing the precise positions thereof with a main sensor, and cutting the graphics areas from the sheet in response to such precise positions.

Abstract: Information as to the location, date and shift of manufacture of roofing shingles is cut into an edge of the shingles as a coded sequence of slits. Preferably, the slit sequence is coded using a binary coding scheme, with a separate binary number group defining each of the shift, the month, the day and the year of manufacture, in addition to plant site identification information. Based on the easily-cut, binary-coded slit sequence, used in conjunction with the plant site identification information, a manufacturer can quickly isolate the time and place of a manufacturing defect. The method of providing a roofing shingle with a coded indication of the shingle's time of manufacture involves arranging a physically-ordered sequence of slit cutting knives, based on a sequence of binary digits, in which a slit cutting knife is provided in the physically-ordered sequence when a corresponding binary digit in the sequence of binary digits is a first value (e.

At least two upper seals are coupled to the frame, each engaging the upper section of one of the lateral edge surfaces and extending approximately the length of the support surface. At least two side seals are also provided and are coupled to the frame, each engaging the side section of one of the lateral edge surfaces and also extending approximately the length of the support surface.

Abstract: In a method of correcting a cutting pattern according to a characteristic of a fabric, a shrinkage ratio of the sponged fabric is measured, and the cutting pattern is corrected according to thus obtained shrinkage ratio data. Since the fabric is sponged, the amount of moisture contained in the fabric is controlled, and the tension applied to the fabric is relaxed, whereby the fabric is restrained from changing its size in the subsequent steps. Also, when shrinkage ratio data taking account of the subsequent fabric processing steps are used for the correction, the cutting pattern can be corrected more accurately.
