This invention relates to improvements in decorative paper and is directed more particularly to improvements in the process of making paper and the product thereof adapted for use in the manufacture of artificial flowers and the like.

The invention has for its principal object the economical provision of paper which has a velvety surface on one side and sheen on its opposite side and which is crimped so that it may be readily formed to produce distinctive yet natural-appearing artificial flowers and the like. The process of this invention is continuous and simple yet efiicient so that cost of production of this novel paper is relatively low.

Various novel advantages and distinctive features of the process of the invention and of the product thereof will be more fully described in connection with the accompanying drawing, wherein:

The figure is a diagrammatic view showing apparatus for carrying out the method of the invention.

It is of importance in considering the merits of my invention that one have some knowledge of the prior art papers used in the manufacture of artificial flowers or the like. The petals of genuine flowers of course have a soft velvety surface on their upper side while their under side is silvery or has a sheen.

Crepe paper of usual form is commonly used for such purposes but this has been found to be unsatisfactory. Not only does crepe paper lack the desirable velvety quality but it also does not have the desired sheen so that artificial flowers .made therefrom do not have a natural appearance. Furthermore, it is necessary in the process of manufacture of crepe paper to wet the web considerably before crimping it. This step tends to cause the colors to run and fade and the paper becomes soft. As a result, the paper looks lifeless and the web is quite likely to be ruptured or injured by the crimping mechanism.

I have found that the type of paper known as velour paper is most suitable for this. purpose. This type of paper has a velvety and fluify quality and it has the soft, vital appearance of living flowers. This is, of course, most desirable in order to eficiently accomplish the purpose intended.

It is a fact however, that a sheet or web of velour paper can not be creped or crimped in the usual manner since the necessary step of wetting the paper before crimping has an unfavorable reaction thereon. But, I have discovered, if a web of velour paper and a web of relatively thin finished or glazed tissue paper are secured together in some manner to form a laminated web the resultant web may be creped as desired.

According to the process of my invention, separate webs V and F of velour paper and of 5 finished or glazed tissue paper are led from separate rolls thereof, V and F, respectively to an adhesive-applying apparatus A of usual form.

This device A preferably has contacting rolls 2 associated therewith as shown and is located ad- 10 jacent the rolls V and F. It is adapted to apply adhesive to the inner side of at least one of the webs. According to the preferred form of the invention the adhesive is applied to the web F of finished or glazed paper.

The two webs V and F are then led into contiguous relation through coacting pressure rolls P which are located adjacent the apparatus A. In this way, the webs may be secured together and a laminated web W is formed. The pressure rolls P may be heated, if desired, but in any event it is necessary in 'order to achieve the best results that the two webs be firmly united throughout.

Then, as the next step in the continuous operation, the laminated web W is led through a wetting or moistening device M whereby the finished or glazed paper side at least is moistened. This device M may consist, as shown, of a suitable tank 4 and roll 6 under which the web W may pass. 30

As the next step, the moistened web W is led to a creping mechanism C which is preferably located immediately adjacent the device M so that the moistening fluid may not soak too much into the web. The device C may include a roll 10 and doctor 8, as shown, of usual form and which is adapted to perform the crimping operation. The creped web W is then ready to be rolled up on a draw-ofi roll or the like D. 40

It may be seen that where the velour paper alone would not react favorably to the wetting process and therefore could not be successfully crimped, the laminated web readily submits to the process. Theresultant product retains all 45 the velvety softness of the velour paper and has a natural appearing sheen on its under surface, while at the same time the creping is readily done Without injury of any kind to the paper, all to the end that a distinctive and improved decorativ paper is provided.

While I have described my process and product thereof in great detail and with respect to preferred embodiments thereof, I do not desire to be limited by such detail or embodiments since varlcured together to provide a laminated sheet, said laminated sheet being creped.

2. As a new article of manufacture, a sheet of velour paper and a sheet of glazed paper secured together to provide a laminated sheet, said laminated sheet being creped.
