Machine for manufacturing uppers for shoes, uppers and shoes manufactured thereby

Abstract

The invention provides a machine (1) for manufacturing a shoe upper (2) for a shoe (3), said machine comprising a reel holder (4); a dial (5); and a top (6); having a vertical Axial and forward and backward moving needle cylinder (7), said needle cylinder has a plurality of grooves (8) inside which needles (9) can slide, said needle selection means ( 10) Controlling said needle; cup-shaped element (11); at least four feeders (12) fitted along the circumference of said machine; guiding means (13); first braking means (14); for recovery a first recovery device (15) for each of said threads (18) to be fed to said needles (9) to form said upper; and a suction hood for unloading said upper (2) (16); said selection device (10) of said needle (9) comprises a preselection cam (95) and a lifting cam (96), said preselection cam defining the corresponding needle (9) and The working path and the non-working path of the heel (85a) of the elastic socket (89) of the auxiliary needle (84), the lifting cam defines the first path for performing the working stitch and is relatively small relative to the first path. Low second pass for performing tuck stitches.

Description

technical field [0001] The invention relates to a machine for manufacturing shoe uppers for shoes, also to shoe uppers, and thus also to shoes manufactured thereby. Background technique [0002] As we all know, today's sports shoes usually include two main elements: the upper and the sole. [0003] Once formed, the upper is fixed to the sole, whose task is to reduce the reaction forces when the user walks, since the sole is made up of different layers, such as, for example, the middle layer of the sole and the tread. [0004] Specifically, the task of the middle layer is to protect the foot and ensure the comfort of the foot, while the task of the tread is to protect the middle layer. [0005] In fact, the tread must be resistant and must ensure maximum traction of the user on the ground. [0006] The upper can be manufactured from different materials, which can be leather, polymer materials, materials on the inside of the upper to improve the comfort of the upper and text...
