摘要:
A method for manufacturing two-color components, particularly for shoes in general, consisting in positioning a sheet-like element (1), made of rubber and the like, in a mold (2) that forms a plurality of cavities (3) delimited by edges (4) the free end whereof lies on the parting plane of the mold. A sheet (5) of plastic material which has a release function is then superimposed on the sheet-like element (1), and a layer (6) is positioned on the sheet in order to give mechanical strength thereto. The mold (2) is then closed with a cover (7), applying pressure together with heating in order to fill the cavities (3) with the rubber and the like and simultaneously move the rubber and the like away from the edges. After removing the layer (6) and the sheet (5) together with any flash of rubber and the like present on the edges, a second sheet-like element (21) is superimposed, and pressure and heating are applied in order to produce bonding with the perforated sheet-like element; after this, the resulting article, which has a two-color appearance, is subjected to vulcanization.
摘要:
A machine (1) for carrying out abrasion tests on materials for shoe soles or on parts of soles or on complete soles comprises a frame (2) with a specimen holder (3, 300), a specimen (4, 400) fixed to the specimen holder (3, 300), an abrasive surface (5), a mobile base block (6) for supporting the abrasive surface (5), the mobile base block (6) being connected to the frame (2), a first cyclical movement mechanism (7) of the mobile support base (6), a second cyclical movement mechanism (8) of the specimen holder (3) towards the abrasive surface (5), the second movement mechanism (8) includes a tie rod of variable length (9) connected to the frame (2) with an actuator (10) to press and allow variable inclinations of the specimen (4, 400) against the abrasive surface (5), and a cleaning device (11) of the abrasive surface (5).

A machine (1) for carrying out tests on a test material(7; 37) comprises a basement (2; 32), a movable rod (3; 33), elements (4; 34) for guiding the rod (3; 33) with respect to the basement (2; 32), a device for the cyclic movement (5; 35) of the rod (3; 33), a support (6; 36) for positioning the test material(7; 37) on the basement (2; 32), and an electronic device (8) for extrapolating data regarding the stress and deformation of the material (7; 37).
摘要:
A high-traction sole unit, comprising a rubber tread (12) and a series of more or less rigid lattice inserts (13), which are separated among them by cavities (A, B, C, D, E) and each of them is composed of undulated elements and a series of inverted T-shaped transverse ribs (15), the axes (151) of which are perpendicular, at the points of relative intersection, to an S-shaped curved line (16) extending from the heel (17) to the toe (18) of the sole unit (11); the lattice inserts (13) are joined together by rubber or elastomeric elements, which are constituted by the same material that constitutes the tread (12) or the wedge of the footwear. To usefully lighten the structure, further ribs (154) of rubber are provided, differing from each other in shape and dimensions, which are suitably located within concavities in the inserts (13); finally the lattice inserts (13) can be constructed of different materials, such as carbon fibre or fibre-filled plastic material or metal materials.
