seen and an apparatus for the manufacture of a cirkuler bikakstetning

摘要

An apparatus is provided for forming a circular, honeycomb-type engine seal from pre-formed core strip having male and female nodes. The apparatus includes a source of strip and means for forming the strip into a circular seal configuration wherein the male and female nodes of the strip are automatically juxtaposed to each other for weldment as relative movement between the forming means and the source occurs to withdraw additional strip from the core strip source. As the relative movement continues, the juxtaposed male and female nodes are exposed to welding head means of the apparatus which welds the male and female nodes to one another. The forming means includes means for causing said relative movement constituted by drive means which is adjustable to permit forming means of different sizes to be utilized. The movement of the forming means permits successive layers or laminae of the strip to be welded to each other in circular form until a seal of the desired dimension is achieved. The method of the invention involves the step of simultaneously welding a plurality of male and female nodes which are juxtaposed to each other, and the additional step of welding pairs of nodes which are interspersed between previously welded pairs and the further step of utilizing the welding of a selected pair of nodes as a signal for the simultaneous weldment of additional pairs.
