DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a method and an apparatus 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 apparatus.
The market today for cloths made from disposable material having extra large widths is considerably less than for corresponding cloths of normal width. Investment and production costs will be very high for producing extra wide cloths if presently available techniques 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.
SUMMARY OF THE INVENTION
The object of the present invention is to solve the problems mentioned, and achieve a method and an apparatus 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 invention relates to a method and an apparatus for producing a material web of synthetic textile material for conversion into table-cloths. Here, two material webs produced according to standard procedure are overlaid and joined along their respective side edges to the sides or the legs of the V of a material web folded to a V shape, for obtaining a total width of the produced web that is greater than the maximum width of a web produced by standard procedure. The inventive apparatus includes two reels on which are wound webs of standard manufacture, which may be rolled off the reels and into mutual proximity with the aid of a roll nip disposed after the reels. A folding plate folds a third web into a V shape, and the third web may be joined to both webs along their respective juxtaposed side edges by the free side less of the V to form a material web having a total width which is greater than the maximum width of a web produced by standard procedure. A web produced in accordance with the method and apparatus includes at least three webs spliced to each other along their respective side edges. At least one web is V-shaped and has its free side portions overlapping and joined to the longitudinal edges of the juxtaposed webs.
Due to the invention there is now enabled a material web of extra large width, using a method that is readily 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 separate, 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 gai
