Abstract
A cross-tufting machine and process for manufacturing carpet. The cross-tufting machine includes a sewing head and a tufting gun. The sewing head is movably mounted on support railing and a support platform is provided to support carpet that is to be provided with a tufted secondary pattern. The carpet moves in steps on top of the support platform in a machine direction and the sewing head traverses back and forth in a cross-wise direction wherein the tufting gun forms the tufted secondary pattern in the carpet.
Claims41
A cross-tufting machine for tufting a secondary pattern into pre-tufted carpet being fed in a machine direction from a feed roll to a take-up roll, the cross-tufting machine comprising:
- a sewing head;
- and
- a tufting gun mounted to the sewing head, the tufting gun comprising one or more needles,
- wherein yarn is fed to the gun and through the one or more needles, and wherein the tufting gun can overtuft the secondary pattern into the pre-tufted carpet at one or more selected pile heights.
A cross-tufting machine for over-tufting pre-tufted carpet, the pre-tufted carpet moving in a machine direction, the cross-tufting machine comprising:
- an over-tufting sewing head movably mounted for movement transverse to the machine direction movement of the pre-tufted carpet.
A process of manufacturing carpet comprising:
- moving a pre-tufted carpet in a machine direction;
- and
- over-tufting a secondary pattern in a direction generally cross-wise to the machine direction.
An over-tufted carpet comprising a base carpet defining a primary pattern, a width, and a lengthwise direction, and an over-tufted secondary pattern extending generally across at least a portion of the width of the base carpet and generally transverse to the lengthwise direction.
An over-tufted carpet prepared by a process comprising the steps of:
- providing an over-tufting machine, the over tufting machine comprising a sewing head having a tufting gun mounted thereto;
- providing carpet, the carpet generally in the form of pre-tufted carpet comprising a primary backing;
- and
- moving the sewing head generally transversely across the carpet as the carpet moves in a machine direction to stitch or tuft a secondary pattern through the primary backing.
A method of tufting a pattern into previously tufted carpet, said method comprising:
- providing a piece of tufted carpet;
- tufting a pattern into the piece of tufted carpet by hand or by machine.
