Embodiment Construction

[0020] refer to Figure 1-3 : A kind of belt-turning mechanism, comprising the folding tube 1 that the tube body gradually draws in from the rear end to the front end, one side of the folding tube is sunken inward, and an outer wrapping cloth is formed between its inner edge and the other side 2 of the folding tube. The first channel 3 through which the bar is bent, and its outer edge forms a second channel 4 for pulling back the turning belt. The front end of the second channel 4 is connected with a hollow liner 5 communicating with it. The opening at the front end constitutes an inlet for the front end of the turning belt to extend into and pull back. There is a gap 7 for the outer cloth strip to pass between the outer edge of the liner 5 and the front outlet of the first passage 3. The upper end of the folding tube is The first serpentine frame 8 for pulling the inner lining elastic band is connected, the rear end of the folding cylinder is connected with the second serpent...

Abstract

The invention relates to a belt-turning mechanism for a sewing machine. The mechanism comprises a folding drum gradually furling from the back end to the front end; one side of the folding drum sinks inwards; a first channel convenient for an outer wrapping strip to bend to pass is formed between the inner edge of the one side and the other side of the folding drum, while a second channel for pulling back a turning belt is formed by the outer edge of the folding drum; the front end of the second channel is connected with a hollow liner tube communicated with the second channel; the front opening of the liner tube is formed into an inlet for stretching into and pulling back the front end of the turning belt; a gap for the outer wrapping strip to pass is reserved between the outer edge of the liner tube and the front outlet of the first channel; the upper end of the folding drum is connected with a first snakelike frame used to guide a liner elastic belt, while the back end is connected with a second snakelike frame used to guide the outer wrapping strip; and the folding drum is connected with an installing device connected with the sewing machine. The invention provides the belt-turning mechanism for the sewing machine which can complete belt turning and has the advantages of automatic manufacture, higher production efficiency and time and labor saving.

Description

technical field [0001] The invention relates to a device used on a sewing machine for making tape turning, in particular to a tape turning mechanism. Background technique [0002] The turning belt includes the outer cloth strip and the inner elastic band. At present, when people make tapes on sewing machines, there is no auxiliary tool for making tapes, which is handmade, that is, the reverse side of the cloth strip used to wrap the elastic band is folded in half longitudinally, and then the upper part of the folded cloth tape is covered. Put on the elastic band, align the edge of the elastic band with the edge of the folded cloth strip, and then use an overlock sewing machine or a herringbone car to carve the folded cloth strip and the edge of the elastic band together. Finally, turn the inner surface of the finished tubular cloth strip to the outside, so that the inner elastic band is made. [0003] The problem existing in the above-mentioned production process is: it is...
