摘要 |
<p>The synthetic resin surfaces to be welded together are guided over a spacer means (2) at a distance past an electrically heated heat source (1) so as to form a heating channel, whereby the surfaces are superficially melted, and are pressed together thereafter. The process and the apparatus are suited especially well for welding sheets, panels, rods and/or tubes of foam material, especially of non-crosslinked low-density polyethylene foam. <IMAGE></p> |
