Abstract (en)
[origin: WO03078124A1] The present invention relates to a method and a mould for manufacturing a plastic element having oppositely arranged eye parts where oppositely one eye part in relation to a substantially centrally placed core/stem is arranged a recess on the opposite side, for example chain links or a conveyor belt. This is achieved by a method where the mould comprises two halves with offset and side placed core/stem parts, which create recesses between side placed eye parts on one side and cavities on the oppositely arranged eye parts, where the ultimate ends of the core/stem parts on one mould half is brought into contact with side placed places interior parts of the core/stem parts on the other mould part by closing the two-part mould. In this manner, pin bolts which until now have shaped the openings in the third dimension become superfluous.
