| 1. | Method for producing a material web of synthetic textile for conversion into tablecloths, characterized in that two material webs produced by standard proce¬ dure are joined along their respective side edges to a material web folded into a V shape such as to obtain a total width of the produced web that is greater than the maximum width of a web produced by standard proce dure. |
| 2. | Method as claimed in claim 1, characterized in that said both first webs are oriented in mutual proxi¬ mity with their side edges directly opposite each other before the respective side edge of each web is spliced to said third material web. |
| 3. | Apparatus for producing a material web of synthe¬ tic textile material for conversion into tablecloths, characterized in that it includes two reels (l, 2) in given, spaced relationship, material webs (3, 4) of standard production being rolled up on said reels, from which said webs are withdrawable into mutual proximity via roll nip (6) arranged for this purpose after said reels, there also being a folding plate (8) disposed before the roll nip (6) for folding a material web (5) , rolled from a reel (7) , into a V shape, the free por¬ tions (12, 13) of this web being joinable to the res¬ pective web (3, 4) along the juxtaposed side edges (9, 10) of these two webs, such as to form a material web (11) having a total width which is greater than the maximum width of a web produced by standard procedure. |
| 4. | Material web of synthetic textile material for conversion into tablecloths, characterized in that the web (11) comprises at least three webs (3, 4, 5) pro¬ duced by standard procedure and joined to each other along respective side edges, at least one (5) of such webs overlapping the longitudinal side edges (9, 10) of the webs (3, 4) with its free portions (12, 13), which are joined to said side edges such as to obtain a total width which is greater than the maximum width of a web produced by standard procedure. |
The present invention relates to a method and an appa- ratus for producing a web of synthetic textile material for making up into table-cloths, and also such a web manufactured according to the method using the appara¬ tus.
The market today for cloths made from disposable mate¬ rial having extra large widths is considerably less than for corresponding cloths of normal width. Invest¬ ment and production costs will be very high for pro¬ ducing extra wide cloths if presently available tech- niques were used for multi-colour styles and printed decorations. A theoretically possible solution to producing such cloth with different colours and print over its width would be to splice two webs, although acceptance by customers would probably be low.
The object of the present invention is to solve the problems mentioned, and achieve a method and an appara¬ tus for producing an extra wide material web, as well as one manufactured according to the method, which by longitudinal splicing of at least three material webs provides a web having a total width complying with the desired, extra wide configuration. The distinguishing features of the invention are disclosed in the accom¬ panying claims.
Due to the invention there is now enabled a material web of extra large width, using a method that is readi¬ ly performed and which is cost-effective by utilizing webs of optional width in optional colours with or without decorative motives. In addition, there is provided in accordance with the invention equipment for
producing a material web for the desired extra wide cloths.
The printed table runner, keeping together the two outer webs of the web produced in accordance with the invention, is traditionally used as a supplementary item loosely placed on top of an ordinary table-cloth. A method functioning technically well in accordance with the invention has been found, however, where this runner is made into an integrated part of the extra wide cloth in its delivery state, but for the observer of the laid table this arrangement can be appreciated as the table runner often placed loosely on top of an ordinary table-cloth for the sake of decoration. With the inventive method large amounts of material are gained, since there is no cloth which is otherwise, or usually, to be found under the runner.
Other advantageous properties of the web in accordance with the invention are that the central web in the form of a table runner with its superior print will be of very high quality, since printing takes place in sepa¬ rate, efficient machinery before splicing this web to the others, which have been dyed in a rational manner in standard equipment. The quality attainable in the final product in accordance with the invention by separately dyeing the different webs is not at all possible to achieve in one and the same machine at present. Several advantages are thus gained by having a central web that can be printed separately before it is integrated into the completed, extra wide web. Finally, in the production of the composite web in accordance with the invention very limited conversion waste is obtained.
The invention will now be described in more detail below with the aid of a preferred embodiment example and with reference to the accompanying drawing, where
Fig. l schematically illustrates an apparatus for producing a material web, in accordance with the in¬ vention, as seen in side elevation,
Fig. 2 is a front elevation of the apparatus illustrat- ed in Fig. 1, and
Fig. 3 is a cross-section along the line A-A in Fig. 2.
As will be seen from the figures, an apparatus for producing a material web 11, in accordance with a preferred embodiment example of the invention, includes two reels 1 and 2 in spaced relationship. On these are wound webs 3 and 4, which may be rolled off towards each other and through a nip 6 situated between the reels. A third web 5, wound onto a reel 7, is fed into the nip 6 after having been folded into a V shape over a folding plate 8 situated above the nip 6. The web 5 passes into the nip with the free ends of its folded sides 12 and 13 between the edge 9 of web 3 and edge 10 of web 4, these two web edges being directly opposite each other. The sides 12 and 13 are caused to overlap the edges 9 and 10 and be joined to them for the pur¬ pose of forming the web 11, which will thus have a total width greater than that obtainable with standard procedure.
Before the web 5, folded into a V shape by the folding plate 8, is fed to the edge portions 9 and 10 of the webs 3 and 4 the free edge portions of its sides 12, 13 are provided with hot melt glue, or other adhesion agent via adhesion agent applicators 14. Before the edge cohesions of the webs 3, 4 and 5, the central web
5, in the illustrated example, is folded in such a way that possible pressure on it is directed inwardly. Both outside webs 3 and 4 are thus joined to the underside of the central web. After longitudinal splicing the composite material web 11 will look like a large cloth provided with a loose table runner.
The procedural method, which decides the implementation of the apparatus, provides a product, i.e. a material web. This web is converted into table-cloths having their upper sides folded inwards at their first longi¬ tudinal folding operation, and this affords advantages both in production and handling. Joining with adhesive takes place in a simple manner, and when the cloth is opened out on a table this is done so that the under¬ side of the web comes against the table. The method of folding also ensures that any decoration on the upper side which could be degraded by scratching is protected by this side being folded inwards.
