Abstract
In the method a surface (2) of an article (1) is provided with adhesive (3) and pressed by a pressure plate (4), inclined by an angle alpha with respect to the surface of the article (1), into said surface (2). In this process, the article is moved over the pressure plate (4), the gap decreasing in the direction of movement. <IMAGE>
Description
(54) IMPROVEMENTS IN OR RELATING TO THE APPLICATION OF
ADHESIVES
(71) We, THE SULBY ENGINEER
ING DEVELOPMENT COMPANY
LIMITED, a British Company of 14 Lombard Road, London SW19 3XN, England, do hereby declare the invention for which we pray that a Patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to the application of adhesives to articles with particular reference to the preparation of the backs of books for receiving a cover. In this specification the word "book" is used to denote a collated assembly of pages to which a cover is applied.
The pages of the book can be stitched or stapled together or simply secured by the adhesive applied to the back.
It is essential, particularly when no stitching or stapling is used, that the adhesive is firmly and intimately applied. The object of this invention is to provide a method and apparatus which ensures the intimate application of the adhesive to the book back with penetration of the adhesive into the fibres of the paper in each page.
According to the present invention there is provided a method of preparing an article for adhesive securement, such method comprising applying adhesive to the article and causing relative movement between the article and a compressive surface, the article and the surface being so inclined relatively to one another that the gap between the article and the surface progressively diminishes during the said movement to compress the adhesive thereby causing it to penetrate into the article, and side walls being provided to confine the book and to prevent the escape of adhesive thereby enhancing the compressing effect.
According to another aspect of the invention an apparatus for carrying out the method described above comprises an element providing the compressive surface, means for moving a book over the said surface with the back thereof spaced from the surface by a gap, the said surface being so inclined that the gap diminishes in the direction of movement, means for introducing adhesive into the said gap, and wall members at each side of the gap to confine the book and prevent escape of adhesive thereby to enhance the compression of the adhesive.
The invention will now be described by way of example and with reference to the accompanying drawings wherein:
Figure 1 is a diagrammatic representation of a book having the back thereof coated with adhesive by the method of the invention;
Figures 2 and 3 are schematic views of an apparatus in accordance with the invention,
Figure 3 being drawn on a larger scale;
Figure 4 is a view of part of the apparatus of Figures 2 and 3 on an enlarged scale; and
Figures 5 and 6 are diagrammatic views similar to Figure 1 indicating alternative methods of applying adhesive to the book back.
Referring initially to Figure 1 a book 1 is depicted as moving in a horizontal plane from left to right in the direction of the arrow
A. The back surface 2 of the book carries a layer 3 of adhesive. A rigid compressing plate 4 is inclined at a small angle a to the horizontal so that the gap between the upper surface of the plate 4 and the book back 1 converges in the direction of the arrow A. As the book 1 moves in the direction of the arrow A the adhesive layer 3 is gradually compressed and during this compression a high pressure of adhesive is attained. The adhesive is thus thoroughly pressed into the back of the book to impregnate the fibres in each sheet of paper. In a typical embodiment of the invention the angle a is 1".
Turning now to Figures 2 and 3 of the drawings a schematic apparatus illustrated therein comprises a compressing plate 10 and guide members 11 and 12 defining walls 13 which confine the pages of the book 1 as it passes therethrough. The guide members 11 and 12 are cut away at the book entry part to define a throat 14 providing a ready entry for the book. The adhesive layer 3 is compressed by the inclined plate 10 in the manner described with reference to Figure 1.
In order to accommodate books of different thicknesses by varying the width of the gap between walls 13 the guide member 12 is adjustably mounted as can be seen best in
Figure 3 of the drawings, the guide member 12 being slidable on plate 1 laterally of the gap, this sliding being controlled by a threaded stem 15.
Viscous liquid adhesive can be applied to the book back by any of the methods illustrated in Figures 4 to 6. In Figure 4, which is a part of the apparatus of Figures 2 and 3, three entry holes 16 for adhesive are provided in the plate 1 in the region of the entry part of the passage defined between guide members 11 and 12.
Alternatively as illustrated in Figure 5 a driven roller 18 partially immersed in a reservoir 17 of adhesive can convey the adhesive as a layer 3 onto the entry end of plate 4. As an alternative as illustrated in
Figure 6 the layer 3 can be conveyed onto the back of book 1 and this is at present the preferred method of applying adhesive.
WHAT I CLAIM IS:
1. A method of preparing an article for adhesive securement, such method comprising applying adhesive to the article and causing relative movement between the article and a compressive surface. the article and the surface being so inclined relatively to one another that the gap between the article and the surface progressively diminishes during the said movement to compress the adhesive thereby causing it to penetrate into the article. and side walls being provided to confine the book to prevent the escape of adhesive, thereby enhancing the compressing effect.
2. A method as claimed in Claim 1 wherein the article is the back of a book.
3. Apparatus for carrying out the method of Claim 2. such apparatus comprising an element providing the compressive surface means for moving a book over the said surface with the back thereof spaced from the surface by a gap. the said surface being so inclined that the gap diminishes in the direction of movement. means for introducing adhesive into the said gap. and wall members at each side of the gap to confine the book and prevent escape of adhesive thereby to enhance the compression of the adhesive.
4. Apparatus as claimed in Claim 3 wherein one of the wall members is laterally adjustable.
5. Apparatus as claimed in either Claim 3 or Claim 4 wherein the means for introducing adhesive into the gap comprises apertures connecting a source of adhesive to the entry of the gap.
6. Apparatus as claimed in any of Claims 3 to 5 wherein the means for introducing adhesive into the gap comprises a driven roller partially immersed in a reservoir of adhesive and communicating a layer of adhesive either to the back of the book or to the compressive surface.
7. A method as claimed in Claim 1 and substantially as hereinbefore described with reference to, and as shown in, the accompanying drawings.
8. Apparatus as claimed in Claim 3 and substantially as hereinbefore described with reference to, and as shown in, the accompanying drawings
