Definitions

  • the invention relates to a bracelet, in particular a jewelry or watch strap, with a band body made of elastomer, as well as several variants for producing the bracelet.
  • the band body consists of a base body and at least one insert body, which are connected by a common in the rubber industry connection method, for example by extrusion coating or pressing.
  • a plastic for example an elastomer
  • a piston through an opening into an inner cavity, referred to as a cavity, of a closably divided first tool.
  • This cavity in the interior of the tool has a negative mold of at least part of a first band body.
  • a second band body which was produced with a second, likewise closable split tool, is implemented or inserted in a specially provided section of the cavity of the first tool. With the introduced through an opening of the first tool elastomer, which is distributed in the remaining cavity, the inserted second band body is encapsulated.
  • Pattern-shaped recesses or recesses on the surface of the tape body are thereby transferred from the tool to the bracelet.
  • more than two tape bodies can be connected to each other by molding, pressing or another connection method.
  • a base body and at least one insert body are made of the same material in a bracelet according to the invention.
  • the bracelet with homogeneous material properties for example, with uniform elongation properties of body and at least one insert body can be equipped.
