Abstract

This invention relates to a method of fastening an edge list comprising plastic material on a wood fibreboard provided with edge portions, the edge list being positioned in a magazine, preferably unrolled to a roll. According to the invention the method comprises the combination of the following moments: the magazine (9) of the edge list is preheated in a suitable way, for instance in an oven, whereafter a part of the edge list (1) is unwound form the roll; the unwound portion of the edge list (1) is heated to such a temperature that the part of the edge list intended to be fastened on the wood fibreboard (4) is melted; the heat-treated portion of the edge list (1) is fixed by pressing to the edge portion (5-8) of the wood fibreboard (4) by a press means (11); the edge list (1) fastened on the wood fibreboard (4) is cooled down by a cooling means (14). The invention also relates to an edge list usable for carrying out the method. This edge list comprises a fastening layer (3) and a wearing layer (2).

Description

Method for fixing an edge list on a wood fibreboard and an edge list for making the method possible.
This invention relates to a method of fastening an edge list to a wood fibre board and an edge list for carrying out the method.
5 It is previously known to fasten edge lists on wood fibre f boards, for instance particle boards. This is made for protec¬ ting the edges of the wood fibre boards. Known edge lists are fastened to the wood fibre boards by glue. These known arrange¬ ments, however, are connected with some problems. Firstly,
10 problems may arise regarding the adhesiveness of the edge list to the wood fibre board. Secondly, problems may arise when using wood fibre boards provided with known edge lists in moist environment. In that connection the problem is that the edge list has a tendency to come loose from the wood fibre board.
15 The purpose of this invention is to eliminate the pro¬ blems with known technique. This has been made possible by the method and the edge list according to the present patent appli¬ cation, which have the moments and the features mentioned in the claims. Due to the invention a so good adhesiveness of the
20 edge list to the wood fibre board is achieved that the wood fibre board provided with the edge list also can be used in a moist environment. Due to the design of the edge list good possibilities are achieved to vary the qualities of the edge list like hardness, friction, resistance to wear etc.
25 The invention shall be described more closely below with reference to the accompanying drawing, where Fiα. 1 schematically shows the design of the edge list, and Fiσ. 2 schematically shows an apparatus for fastening the edge list to a wood fibre board.
Referring to Fig. 1 iε schematically shown there the new
30 edge list 1. This one comprises two layers, i.e. a wearing layer
2 and a fastening layer 3. Both layers 2, 3 comprise plastic material of the type thermoplastic polyurethane. In that connec-
Φ tion the plastic material of the fastening layer has a lower melting point than the plastic material of the wearing layer. * 35 As is apparent from the names, the fastening layer 3 comprises that part of the edge list 1 which is intended to be fastened to the wood fibre board and which accordingly is intended to be directed inwards towards the plate. Thus, the wearing layer 2 comprises that part of the edge list which is intended to be directed outwards from the wood fibre board and which comes into touch with the environment. This wearing layer 2 ought to be hard and may in a suitable way be made hard, for instance by addition of glass balls as reinforcement means to the layer.
In Fig. 2 is schematically shown the apparatus for fastening the new edge list 1 onto a wood fibre board 4 com¬ prising two longitudinal edge portions 5, 6 and two transverse edge portions 7, 8. In this connection the edge list is rolled up to a roll in a list magazine 9. Furthermore, the apparatus is so made that the wood fibre board 4 in an essentially vertical position, in this case with its one longitudinal edge portion 5 positioned at the very bottom, is intended to slowly move for- wards in the direction of the arrow P, while the edge list 1 is applied to the longitudinal edge portion 5. In that connection the edge list 1 is unwound from the list magazine 9 with essentially the same velocity as the wood fibre board 4 moves forwards. According to the preferred embodiment of the apparatus in Fig. 2 the edge list 1 is intended to be fastened on the wood fibre board from below. Thus, the edge list 1 is so rolled up in the list magazine 9 that the fastening layer 3 of the edge list, which layer is intended to hold the list on the wood fibre board, is directed outwards on the roll. The apparatus according to Fig. 2 comprises a not shown pre-heating means which may comprise an oven or the like. Furthermore, the apparatus comprises a heating means 10 which in this case is positioned above the edge list 1 and accordingly heats up its fastening layer 3 still more. This heating means 10 shall give such a temperature that the plastic material of the fastening layer 3 melts, but not so high temperature that the wearing layer 2 melts. Since the wearing layer has a higher melting temperature than the fastening layer, the wearing layer functions as a carrier during the actual fastening procedure of the edge list. The edge list 1 is intended to be fixed by pressing to the edge portion 5 of the wood fibre board 4 by a stationary press means ii. This press means in this case com¬ prises two press rolls 12, 13 which are oriented essentially horizontally and essentially perpendicularly to the motion di- rection P of the wood fibre board 4 and which are intended to rotate in a clockwise direction. In front of the press means 11, seen in the direction of the arrow P, is a cooling means 14 arranged. This cooling means, which may comprise a metal plate provided with a layer of Teflon, is intended to cool down the edge list 1 and the lower portion of the wood fibre board 4 after the fastening procedure of the edge list by pressing.
The fastening of the edge list to the wood fibre board is made in the following way: The list magazine 9 is preheated in a suitable way to about
100°C. Then a part of the edge list 1 is unwound from the roll, the unwound portion of the edge list being subjected to heating to such a temperature that the fastening layer 3 of the edge list 1 is melted. Thereafter the heat treated portion of the edge list is applied to the lower, longitudinal edge portion 5 of the wood fibre board 4 by the press means 11. Due to the fact that the fastening layer 3 of the edge list 1 is in a melted condition, there arises a very good mechanical attachment of the edge list when fastening the same in the porous material of the wood fibre board by pressing. In the order to further increase the strenght of the adhesiveness, there is an immediate cooling of the edge list and the lower portion of the wood fibre board by the cooling means 14.
As a rule the wood fibre board 4 all around shall be provided with edge lists. This is made possible by the fact that the board 4 is turned 90° in the vertical plane after the edge portion 5 having been provided with the edge list, whereby the transverse edge portion 7 takes the position of the longitudinal edge portion 5 and is provided with the edge list and so on. In the text the expression "wood fibre board" has been used. This expression covers different types of wood fibre boards, for instance particle boards. The invention is of course not limited to what has been shown and described but can be modified within the scope of the following claims. Thus, the edge list can be fastened on the wood fibre board not only from below but also from above or from the side.
