Abstract
A tie-tipping apparatus is provided for the sewing and finishing of tie t and the use of same through the use of properly modified and integrated sewing machines. The apparatus includes a base and a cover, each of similar form to the tie tip. The fabrics to be sewn are positioned between the base and the cover and, by the use of a lever system, instruments of friction are shifted, properly placed on the cover, which pull the upper fabric and take it to assume a configuration which allows for the sewing through an appropriate sewing slot. The tie-tipping apparatus permits an easier positioning of the fabrics, and the possibility to regulate the sewing rim in a different way along the sides of the tip and along the flanks and the possibility of use in an automated work circuit.
Claims33
A tie-tipping apparatus for sewing together an upper fabric with a lower fabric forming a sewing rim therebetween, said upper fabric and said lower fabric each having sides, said apparatus comprising a base shaped with a contour similar to a tie tip, on which said base the fabrics are disposed on the top of each other in such a way that the sides of both the fabrics coincide, said base having a continuous sewing slot following its contour and an attrition means disposed next to at least a part of said sewing slot;
- said sewing slot having a plurality of corners, said tie-tipping apparatus further having a cover hinged and shaped similarly to said base, said cover having an upper face and a lower face, tip sides and flank sides defining a contour with dimensions substantially coincident to said sewing slot in said base;
- said tie-tipping apparatus further having a friction means mounted to the lower face of said cover, said friction means being transactionally movable by a lever mechanism attached to said upper face of said cover as to form pinches on the upper fabric at the tip and at said corners of said sewing slot.
