Problems solved by technology

Furthermore, the use of laser devices for the stated purpose is very costly and, in connection therewith, the fact of their introduction into existing production lines presents considerable difficulties
In particular, the operation of laser devices is quite energy-intensive and therefore very uneconomical

Embodiment Construction

[0106] In the following, specific embodiments of the present invention are compared with conventional methods for joining edge strips to plate-shaped workpieces and the edge strip workpieces obtained thereby. In particular, the method according to the invention and the workpieces obtained by this method are compared with the method of heating the adhesive layer by UV radiation, IR radiation, hot air blower, microwave and laser radiation and the workpieces obtained thereby.

[0107] In all tests, edge strips with a width of 3 cm and a length of 2 m were joined to narrow 2 cm wide chipboard decks and subsequently milled and rinsed.

[0108] In the first series of tests, the edge strips were first treated with an adhesive promoter (primer) and supplied with one of two different commercially available hotmelt adhesives from the company Jowat, Deltmund, Federal Republic of Germany (eg by knife coating, spraying, rolling, etc.). Remelting (activation) of hotmelt adhesives is achiev...

Abstract

The invention relates to a method for applying edge strips (edge tape) onto narrow surfaces (narrow sides) of plate-shaped work pieces (material parts) by joining, wherein the edge strip is applied with a glue that can be activated by heat and is heated by plasma radiation. The invention further relates to the materials to which edge strips have been applied obtained in said way and to a device for carrying out said method.

Description

technical field [0001] The present invention relates to a technique for joining edge bands on the surface of workpieces. [0002] More particularly, the invention relates to a method of joining edge bands by joining at least one narrow face of, in particular panel-shaped workpieces, as well as workpieces obtained by the method of the invention and devices for carrying out the method of the invention. [0003] The invention further relates to the use of plasma to join edge bands on narrow faces, in particular panel-shaped workpieces. technical background [0004] In the prior art there are a large number of known methods for joining edge strips on the narrow side of panel-shaped workpieces. [0005] On the narrow side of panel-shaped workpieces, a through-travel machine, such as an edge folding machine, is usually used to connect the edge strips by means of edge glue assembly. The edge strip in question is supplied to this device, for example, from a hopper, and the hot mel...
