A method and apparatus is disclosed for forming a moulding. A material (23') comprising magnetic particles is injected into a mould (10) and a magnetic field is applied to at least a portion of the material (23') comprising magnetic particles so as to change the orientation and/or distribution the magnetic particles in the moulding material (23'). One or more further materials (24) may be injected into the mould (10) to form a multi-layered moulding. The further materials (24) may comprise magnetic particles.

摘要:
There is provided a leader tape(5) which is capable of preventing breakage of a tape body(11) when the tape body(11) is pulled out, and a tape cartridge(1) incorporating the leader tape(5). A leader tape(5) includes a tape body(11) having one end fixed to a tape(4), for enabling the tape(4) to be pulled out of a cartridge body(2), and a pin member(12) attached to the tape body(11), for pulling out the tape(4) therewith. The tape body(11) has a portion on a side of another end opposite to the one end, the portion being folded such that the folded portion surrounds the periphery of the pin member(12) and that the folded portion has a leading end portion(11b) thereof welded to a tape surface of the tape body(11) opposed to the folded portion. The welding is effected non-densely in at least one of a pin member-side boundary portion(S1a) of a welded area(W1) where the leading end portion and the tape surface opposed thereto are welded to each other and a one end-side boundary portion(S1b) of the welded area (W1).
摘要:
The invention relates to a method and a device for connecting moulded parts, one of said moulded parts consisting of a non-metallic material, by means of at least one adhesive seam consisting of an adhesive which can be hardened by heat. Said moulded parts are respectively inserted, at least in regions, into metallic moulds, at least one of said moulds being provided with a groove along the region of the adhesive seam. The adhesive seam is applied, the metallic moulds and the moulded parts are compressed, and the adhesive seam is heated. The inventive method enables a solution to be created, by which means the necessary heating of the adhesive seam can be carried out between two moulded parts arranged between two metallic moulds in the shortest amount of time possible, in order to accelerate the course of the method. In order to achieve this, a microwave line is inserted into the groove of one of the metallic moulds, and once the metallic moulds and the moulded parts have been compressed, microwaves are introduced into the groove by means of the microwave line in order to heat the adhesive seam absorbing the microwaves.
