A shoe tongue manufacturing process

Abstract

The invention discloses a shoe tongue making process. The shoe tongue making process comprises the steps of forming a wall groove in the thickness face of the top end of foam, wherein the distance between the wall groove and the outer surface of the foam is 2-3 mm; overlaying a tongue face with a tongue lining, and processing the top end of the tongue lining and the top end of the tongue face to form a joint portion; sewing the tongue lining and the tongue face together along the lower side of the joint portion; spraying glue onto the inner surface of the tongue face for enabling the tongue face to be attached to the foam, wherein the top end of the foam is located below a sewing thread by a distance of 2-3 mm; overturning the tongue lining to wrap the foam, guiding the joint portion into the wall groove by means of an auxiliary tool during overturning, and making the arc at the overturning position between the tongue lining and the top end of the foam smooth by means of an auxiliary tool; opening the lower end of the tongue lining, spraying glue onto the inner surface of the tongue lining and / or the back side, facing the tongue lining, of the foam, and laminating the tongue lining and the foam after glue spraying; and conducting sewing with a sewing machine along the lower-end arcs of the tongue lining and the tongue face, so as to form a closed sewn structure. By the adoption of the shoe tongue making process, the arc of the upper end of a shoe tongue can be smooth, and quality is stable and controllable due to the adoption of standard operation.

Description

technical field [0001] The invention relates to the technical field of footwear, in particular to a shoe tongue manufacturing process. Background technique [0002] The tongue, as an important part of the shoe, is generally located on the instep of the shoe. It covers the foot and plays a certain protective role. At the same time, the tongue can also slow down the friction of the shoelace on the instep, which greatly affects the Consumers' feelings and evaluations of the appearance and comfort of shoes. The tongue is composed of the inner tongue, the tongue surface and foam, and the foam is sandwiched between the tongue inner and the tongue surface. In the traditional production method of the tongue, such as the Chinese patent publication (CN102206899B), the tongue needs to be firstly connected to the top and The tongue surface is sutured and then turned over to cover the foam, and because the upper end of the tongue is 3mm to 5mm longer than the tongue surface, the radian ...

Problems solved by technology

The tongue is composed of the inner tongue, the tongue surface and foam, and the foam is sandwiched between the tongue inner and the tongue surface. In the traditional production method of the tongue, such as the Chinese patent publication (CN102206899B), the tongue needs to be firstly connected to the top and The tongue surface is sutured and then turned over to cover the foam, and because the upper end of the tongue is 3mm to 5mm longer than the tongue surface, the radian of the upper end of the tongue is not easy to arrange when turning over, which is inefficient and not round and smooth, which affects the appearance
