Abstract
An apparatus and method for automatically stitching a material portion by moving the material portion over a sewing table relative to a sewing head. In particular, the present invention includes a structure, device, or other mechanism for reducing friction between the material portion and the sewing table, whereby the material portion is more easily movable over the sewing table. The present invention especially relates to the manufacture of mats having a non-skid backing which would otherwise be very difficult to move relative to a sewing head for sewing the mats.
Claims53
A sewing mechanism for sewing a material portion, comprising:
- a sewing head;
- a sewing table providing a sewing surface along which the material portion is moved during sewing;
- a material portion moving mechanism constructed and arranged to move the material portion along said sewing surface relative to the sewing head;
- and
- a friction-reducing member provided between the material portion and said sewing surface so as to facilitate moving the material portion with said material portion moving mechanism, the friction-reducing member being arranged to move with the material portion.
An apparatus for manufacturing a mat having an edge binding, comprising:
- a mat material supply constructed and arranged to supply a web of the mat material;
- a drawing mechanism constructed and arranged to draw the web along;
- a die cutter including a die shaped to cut a mat from the web;
- a sewing mechanism for providing a binding on an edge of each mat, comprising:
- a sewing head;
- a sewing table providing a sewing surface along which the mat is moved during sewing;
- a mat moving mechanism constructed and arranged to move the mat along said sewing surface relative to the sewing head;
- and
- a friction-reducing member provided between the mat and said sewing surface so as to facilitate moving the mat with said mat moving mechanism.
A method for sewing a material portion, comprising the steps of:
- providing a friction-reducing material sheet between the material portion and a sewing surface to facilitate movement of the material portion over the sewing surface during sewing;
- and
- moving the material portion and the friction-reducing material sheet over the sewing surface relative to a sewing device while sewing the material portion with the sewing device.
