Description

DESCRIPTION POLYPROPYLENE (PP) EDGE BAND WITH FUNCTIONAL LAYER AND THIS A PRODUCTION METHOD RELATED TO THE PRODUCT Technical Area Invention, table, cabinet, etc. It concerns edge bands used on furniture.

In particular, the invention includes laser, plasma, hot air, near infrared spectroscopy (NIR), microwave. etc. polypropylene (PP) edge band containing fusible functional layer with welds and this with a production method that allows the edge band to be produced with the coextrusion technique. Prior Art Table, cabinet, etc. edge bands in different colors and features on furniture is used. Relevant edge bands can be in plain or patterned colours. Moreover They can be produced from different materials such as melamine, ABS, PVC.

Existing edge bands are formed on the junction line after being glued to the chipboard. Image defect occurs due to space. Also between the edge band and the chipboard. When it is desired to increase the adhesion strength, the existing production techniques cannot provide a solution.

Another drawback is that in the current situation the glue is primarily heated in a crucible at high temperature. After it is melted and applied on the chipboard, the edge band glued chipboard in a split second. It is adhered to the surface by pressing. It is mandatory to use a metal crucible for glue, It is waited for at least one hour for the glue to melt and the dried metal sticks to the inner surface of the crucible. Due to the glues, the crucible is constantly cleaned every day. Time and production losses is formed. Worker safety during cleaning as the crucible is at high temperature problems occur.

There is no separate layer of glue on the existing edge bands, glue, edge band chipboard When it is applied on the chipboard, it is applied on the chipboard and the edge banding is applied within seconds. Adhesion is provided by pressing on the glue. However, currently the furniture For example, if the manufacturer has a laser machine, only laser melt glue is available for that manufacturer. production is made using Therefore, there is no production flexibility.

In the patent research, the subject of the invention is polypropylene (PP) edge band and this edge No patent has been found describing the coextrusion method used for the tape. However Some patents made in the related technical field are explained below. Similar to the invention in the previous art, TR2018/11715 belonging to the applicant company Patent application no. The aforementioned patent application, laser, plasma and Edgebanding with hot melt adhesive layer and production of this edgebanding It relates to a coextrusion method used for However, the related product contains an ABS layer. It is an intermediate layer to provide an inseparable bond between the ABS layer and the glue layer. It is obligatory to use a primer layer. This situation adds to the additional material cost, additional causes process and production difficulties.

The patent application numbered TR2010/06145 is about PVC edge bands used in furniture production. PVC that facilitates visual inspection whether it contains color difference, scratches and color difference. It is related to the edgeband control assembly.

European Patent Application publication number EP1641618B1 against the edge of a panel a print that is pressed and moved across it to move the print roll an edge to the edge of a contoured panel of predetermined thickness via the roller An edgebanding modification that follows an edgebander applying the tape relates to the tool.
