Abstract
The invention relates to a method and to a device for producing a boat-type body (10) of a water sport device. According to the invention, a rotating frame (12), which is pre-formed about an access opening of the boat-like body (10), is arranged on an inner side of a negative mould. The outer shape of the boat-type body (10) is predetermined, essentially, by the innerside of the negative mould. The boat-like body (10) is produced in the inner side of the mould by means of a thermoplastic shaping method. During the shaping process, at least one part of the surface of the rotating frame (12) is in contact with the boat-like body (10) which is formed by the thermoplastic shaping method. The invention also relates to a water sport device.
Claims17
A method for producing the hull of a piece of water sports equipment, the method comprising arranging a premolded frame (12) on an inner surface of a negative mold, such that the outer shape of the hull (10) is predetermined by the inner surface of the negative mold;
- producing the hull (10) on the inner surface of the mold by a thermoplastic molding process;
- and, during the molding operation, contacting at least part of the surface of the frame (12) with the hull (10) that is being molded by the thermoplastic molding process;
- wherein a connection is produced between the frame (12) and the hull (10), so that the frame (12) is positioned around a cockpit opening of the hull (10).
A method for producing the hull of a piece of water sports equipment, the method comprising arranging a premolded frame (12) on an inner surface of a negative mold, such that the outer shape of the hull (10) is predetermined by the inner surface of the negative mold;
- producing the hull (10) on the inner surface of the mold by a thermoplastic molding process;
- and, during the molding operation, contacting at least part of the surface of the frame (12) with the hull (10) that is being molded by the thermoplastic molding process;
- wherein a connection is produced between the frame (12) and the hull (10), so that the frame (12) is positioned around a cockpit opening of the hull (10), wherein an additional premolded element (24) is arranged in the mold, such that the additional premolded element is a handle (24, 26), wherein the handle (26) has a base plate, which is joined with the hull (10) by the thermoplastic molding process, where the base plate contains a bilge hole (28), which is tightly plugged by a bilge plug (29).
A method for producing the hull of a piece of water sports equipment, in which a preform with at least two layers is produced, wherein the first layer consists of a material of a first color, and the second layer consists of a material of a second color, and in which the preform is placed in the mold and molded by a thermoplastic molding process in such a way that at least the outer layer of the upper part of the hull (10) has the first color and at least the outer layer of the lower part of the hull has the second color, wherein a premolded frame (12) and/or another premolded element (24, 26) is introduced into the hull (10) by arranging the premolded frame (12) on the inner surface of a negative mold, such that the outer shape of the hull (10) is predetermined by the inner surface of the negative mold;
- in which the hull (10) is produced on the inner surface of the mold by a thermoplastic molding process;
- and in which, during the molding operation, at least part of the surface of the frame (12) is in contact with the hull (10) that is being molded by the thermoplastic molding process;
- wherein a connection is produced between the frame (12) and the hull (10), so that the frame (12) is positioned around a cockpit opening of the hull (10).
