摘要:
According to one aspect, the shoe sole (10) comprises at least one main ground engagement section (22) specifically designed to respond to certain modes of solicitation by the foot of the player. Such section is provided with a sculpted pattern having recesses (102) and solid areas (100). The recesses and solid areas are distributed to minimize pressures or stress differences throughout the ground engagement section concerned so as to provide better adherence and lower wear by abrasion in response to such mode of solicitations. Preferably this arrangement is applied to more than one main ground engagement section (22, 24, 42, 44) in the shoe sole, each of which offers a specific response to a particular mode of solicitation by a player in action. According to a preferred embodiment the recesses are made of elongated cells opening (102) in a corresponding solid area through an elongated aperture (101) with rounded ends (108). The application of these principles to the production of a tennis shoe is described.

Tread for a tyre for a two-wheel vehicle improving grip when running on a usage surface liable to become slippery; this tread comprising blocks (1, 2, 3) separated from one another by grooves (4), each block comprising a contact face (10, 20, 30) intended to come into contact with the usage surface as the tyre is running and lateral faces intersecting the contact face to form edge corners delimiting a contour of the contact face having a geometric shape with at least three branches, each branch (11, 21, 31) ending in a point (110, 210, 310) the angle of which is at least equal to 20 degrees and at most equal to 90 degrees, the branches (11, 21, 31) of each block (1, 2, 3), considered two by two, between them determining setback parts (12, 22, 32), each block (1, 2, 3) being provided with slits (111, 112, 113; 211, 212, 213; 311, 312, 313) terminating at one of their ends in one of the setbacks formed on the face of the block and at a same location at their other end so as to create elementary patterns comprising at least two points of the contact face, the said elementary patterns of one and the same block interacting by contact with one another as they pass through contact with the usage surface. Furthermore, in at least part of the tread, the blocks (1, 2, 3) have orientations that are angularly offset from one another according to their axial position with respect to the equatorial median plane.

This adhesion chain for the wheel of a motor vehicle comprises an adhesion tread intended to be in contact with at least the tread of the wheel concerned, and kept in place by means of respectively external and internal tensioning cables. The adhesion tread consists of a net prepared from textile material, said net being prepared by knitting of cords themselves prepared by knitting, so as to define the meshes of said net, and in that the cords include a reinforcing core from a high-modulus material.

Footwear with a sole formed from an elastomeric material whose grip is improved on ground where the interface may include an intermediate foreign substance, this sole comprising lugs (31) separated from each other by grooves (35). The walls of the grooves (35) are cut into the thickness of the elastomeric material and delimit patterns with sharp angles in the profile of said lugs (31) which can pierce said foreign substance to establish direct dry contact between the two surfaces. Each lug (31) forms a star-shaped pattern having at least five arms in the form of stems (32) distributed over its, profile and each stem (32) is orientated radially towards the outside of the pattern and terminates in an end. Each stem (32) is separated from its neighbor by a recess (38) in the profile of the lug. Finally, each lug (31) has a stem (32) engaged in a space of the adjacent groove (35) which is delimited by a recess (38) between two neighboring stems in the profile of a second lug neighboring the first lug.
摘要:
The machine for manufacturing a tire carcass half-reinforcement from a single filament wrapped around a bead wire which includes: bead wire holders operated by actuating cylinders, allowing said bead wire to be held in a predetermined position; a ring which has half as many hooks as there will be arches of carcass filament contained in the tire that is to be manufactured, the ring being held a predetermined distance away from said bead wire; a reel of filament which is moved in the central space of the bead wire, wrapped around it, the path crossing the plane of the ring and passing radially inside it; and a mechanism for hooking the filament onto each of the hooks.
