Quilted fabric panel cutter
An apparatus for cutting a quilted material web having a quilted patterns thereon into panels having a desired length and width with respective quilted patterns centered therein. A first detector detects a center of a quilted pattern on the quilted material web; and in response thereto, a cutting apparatus cuts the quilted material web to form edges of a panel equidistant from the quilted pattern center. The cutting apparatus includes a pair of trim blades that cut opposite side edges of the panel equidistant from the quilted pattern center and a cross cutting apparatus that cuts end edges of the panel equidistant from the quilted pattern center.
1. A method of cutting a quilted material web having quilted patterns into panels, each of the panels having a width and a length with a respective quilted pattern disposed therein, the method comprising:
applying center marks to the quilted material web, the center marks identifying centers of respective quilted patterns;
providing a cross cutting apparatus for cutting end edges of respective panels;
providing an edge detector for detecting end edges of respective panels;
providing a trimming apparatus for cutting side edges of the panels;
providing a center detector for locating the centers of the quilted patterns by detecting the center marks;
moving the center detector to a position longitudinally displaced from the cross cutting apparatus by a distance substantially equal to one-half the length of a panel;
moving the quilted material web in the longitudinal direction;
detecting a position of a center mark;
stopping motion of the quilted material web in response to detecting the position of the center mark;
transversely centering the trimming apparatus relative to the center of the panels in response to the detecting of the position of the center mark;
operating the cross cutting apparatus to form a first end edge of the panel;
moving the edge detector to a position longitudinally displaced from the cross cutting apparatus by a distance substantially equal to the length of the panel;
moving the quilted material web in the longitudinal direction;
operating the trimming apparatus to simultaneously longitudinally cut opposed side edges of the panel substantially equidistant from the center of the panel;
detecting the first end edge with the edge detector;
stopping motion of the quilted material web in response to detecting the first end edge; and
operating the cross cutting apparatus to form a second end edge of the panel, the first end edge and the second end edge being equidistant from the center of a panel.
2. The method of claim 1 wherein the quilted pattern is formed of chain-stitch sequences having a finish side on one side of the quilted material web, and the applying the center marks includes applying the marks to the side of the web that is opposite to the finish side of chain stitches forming the pattern.
3. The method of claim 2 wherein the applying of the marks includes printing the center marks on the side of the web opposite said finish side.
4. A method of cutting a quilted material web having quilted patterns into panels, each of the panels having a width and a length with a respective quilted pattern disposed therein, the method comprising:
applying center marks to the quilted material web, the center marks identifying centers of respective quilted patterns;
moving a center detector to a position longitudinally displaced from the cross cutting apparatus by a distance substantially equal to one-half the length of a panel;
moving the quilted material web in a longitudinal direction;
detecting a position of a center mark with the center detector;
stopping motion of the quilted material web in response to the detecting of the position of the center mark;
transversely centering a trimming apparatus relative to the center of the panels in response to the detecting of the position of the center mark;
operating a cross cutting apparatus to form a first end edge of the panel;
moving an edge detector to a position longitudinally displaced from the cross cutting apparatus by a distance substantially equal to the length of the panel;
moving the quilted material web in the longitudinal direction;
operating the trimming apparatus to simultaneously longitudinally cut opposed side edges of the panel substantially equidistant from the center of the panel;
detecting the first end edge with the edge detector;
stopping motion of the quilted material web in response to detecting the first end edge; and
operating the cross cutting apparatus to form a second end edge of the panel, the first end edge and the second end edge being equidistant from the center of a panel.
5. The method of claim 4 wherein the quilted pattern is formed of chain-stitch sequences having a finish side on one side of the quilted material web, and the applying the center marks includes applying the marks to the side of the web that is opposite to the finish side of chain stitches forming the pattern.
6. The method of claim 4 wherein the applying of the marks includes printing the center marks on the side of the web opposite said finish side.
