Abstract:
The invention relates to a method for the production of a sole (3) having at least one cleat (1), wherein the cleat (1) is arranged at the bottom side (2) of the sole (3). To improve the demoulding of the sole supplied with cleats from the injection molding tool, the invention comprises the steps: a) Production of at least on cleat (1), wherein the cleat (1) has a cleat base body (4) which can be connected with the sole (3), wherein at least one extension (5) is arranged at the cleat base body (5) which extents toward the ground; b) Inserting of the cleat (1) in a holding part (6), wherein the holding part (6) has a congruent receiving space (7) for at least a part of the cleat base body (4) and for the extension (5); c) Placing of the cleat (1) together with the holding part (6) in a recess (8) in a at least two-part injection molding tool (9, 10), so that a part of the cleat (1) projects into the cavity (11) which is formed between the parts of the injection molding tool; d) Injection molding of at least a part of the sole (3) by injecting of plastic melt into the cavity (11) of the injection molding tool (9, 10), so that a part of the cleat (1) is coated by the plastic melt; e) Demoulding of the injection-molded sole (3) together with the coated cleat (1) and the holding part (6); f) Removing of the holding part (6) from the cleat (1).
