Abstract
An overtufting machine/method provides additional yarn per area in an area of design than in areas lacking the overtufted design. Specifically, for many embodiments, a carpet is first tufted, and then run past an overtufting station which preferably moves in a lateral direction relative to the direction of feed to direct at least one needle through the carpet in at least one selectable height option. Rails are preferably used to shuttle the needle supported by a head on at least one carriage to shuttle along the rail(s).
Claims20
An overtufting machine comprising:
- a) a pre-tufted input roll of carpet feeding to an output roll in a direction of feed;
- b) at least one rail directed at least somewhat laterally relative the direction of feed;
- c) at least one carriage supporting at least one head with at least one needle operably coupled to the rail and movable at least laterally relative to the direction of feed along the at least one rail, said at least one needle configured to stitch intermediate pre-tufted loops of the tufted carpet with at least a portion of a design to provide a higher stitch count density in an area of the at least a portion of the design than in areas not having the at least a portion of the design.
An overtufting machine comprising:
- a) an input roll feeding to an output roll in a direction of feed, said output roll having tufted carpet thereon;
- b) at least one rail directed at least somewhat laterally relative the direction of feed;
- c) a first station tufting a design to provide the tufted carpet;
- d) downstream in the direction of feed and spaced from the first station, at least one carriage supporting at least one head with at least one needle operably coupled to the rail and movable at least laterally relative to the direction of feed along the at least one rail, said at least one needle configured to stitch intermediate pre-tufted loops of the tufted carpet with at least a portion of a design to provide a higher stitch count density in an area of the at least a portion of the design than in areas not having the at least a portion of the design.
