Abstract
An apparatus for trimming the edges of a fabric panel. The apparatus includes a holding fixture for holding the panel such that the edges to be trimmed hang freely in the holding fixture. A trimming apparatus is insertable into the holding fixture for trimming the edges of the panels together while the panels are held in the holding fixture. The trimming apparatus includes a frame having a movable slide and at least one trimming assembly attached to the slide. A fixture drive engages the holding fixture holding the edges of the panels to be trimmed and repositions the holding fixture prior to trimming the edges of the panel.
Claims9
A fabric trimming apparatus, said apparatus comprising:
- (a) a frame having a movable slide and a holding fixture having a holding surface for holding a fabric panel;
- (b) at least one trimming assembly attached to the slide, said trimming assembly including a circular blade, a matching anvil, and a drive means connected to said circular blade and said anvil;
- and
- (c) means for aligning said fabric edges prior to trimming, said means including an edge lifter with a vacuum chamber for lifting freely hanging edges of a fabric panel away from said holding fixture and towards said vacuum chamber with a vacuum during trimming with said at least one trimming assembly, said edge lifter being generally linearly aligned with said surface of said holding fixture and perpendicularly aligned with said circular blade;
- wherein said edge lifter lifts the freely hanging edges into alignment with a portion of the fabric panel on the holding fixture surface, wherein said fabric is first clamped in said holding fixture and then aligning said edges with said vacuum chamber prior to trimming.
An apparatus for trimming a fabric panel along edges of said fabric panel, said apparatus comprising:
- (a) a holding fixture having a surface for holding said panel such that the edges of said fabric panel hang freely in said holding fixture;
- (b) an edge lifter with a vacuum chamber for lifting the freely hanging edges of said fabric panel away from said holding fixture and towards said vacuum chamber with a vacuum during trimming, said edge lifter being generally linearly aligned with said surface of said holding fixture wherein said edge lifter lifts the freely hanging edges into alignment with a portion of the fabric panel on the holding fixture surface;
- (c) a trimming apparatus insertable into said holding fixture for trimming the freely hanging edges of said panels while said panel is held in said holding fixture and the freely hanging edges of said panels are lifted away from said holding fixture with said edge lifter, said trimming apparatus including (i) a frame having a movable slide;
- and (ii) at least one trimming assembly attached to the slide, said trimming assembly including a circular blade, said circular blade being perpendicularly aligned with said edge lifter;
- a matching anvil;
- and a drive means connected to said circular blade and said anvil;
- and
- (d) a fixture drive for engaging said holding fixture and repositioning said holding fixture prior to trimming the edges of said panel.
An apparatus for trimming a fabric panel along edges of said fabric panel, said apparatus comprising:
- (a) a holding fixture having a surface for holding said panel such that the edges of said fabric panel hang freely in said holding fixture;
- (b) a trimming apparatus adapted to be inserted into said holding fixture for trimming the edges of said panels together while said panel is held in said holding fixture, said trimming apparatus including (i) a frame having a movable slide;
- and (ii) at least one trimming assembly attached to the slide, said trimming assembly including a circular blade, a matching anvil, and a drive means connected to said circular blade and said anvil;
- (c) a fixture drive for engaging said holding fixture and repositioning said holding fixture prior to trimming the edges of said panel;
- and
- (d) an elongated edge lifter having a vacuum chamber located adjacent to said trimming assembly, said vacuum chamber for lifting the freely hanging edges of said fabric panel away from said holding fixture and towards said vacuum chamber with a vacuum during trimming with said trimming apparatus, said edge lifter being generally linearly aligned with said surface of said holding fixture and perpendicularly aligned with said circular blade, wherein said edge lifter lifts the freely hanging edges into alignment with a portion of the fabric panel on the holding fixture surface.
