Abstract
METHOD AND APPARATUS OF MAKING VENETIAN BLIND SLATS
ABSTRACT OF THE INVENTION
Method and apparatus of making venetian blind slats utilizes two layers of fabric to enclose slat by the steps of pressing said layers of fabric and slat together while heating, cooling said laminated slat, and rolling said laminated slat. The laminated slat so made can preserves the nature of the fabric, and can save considerable amount of materials and labors, the latter is even more advantages.
ABSTRACT OF THE INVENTION
Method and apparatus of making venetian blind slats utilizes two layers of fabric to enclose slat by the steps of pressing said layers of fabric and slat together while heating, cooling said laminated slat, and rolling said laminated slat. The laminated slat so made can preserves the nature of the fabric, and can save considerable amount of materials and labors, the latter is even more advantages.

BACKGROUND OF THE INVENTION
__________ _____.___________ S A klnd of the venetian blind slats, which is using two layers of fabric laminated with conventional slats in between, then heating said laminated slat while pressing, consequently, cool it by air or any sufficient means, finally, applying rollers to obtain slats suitable for uses in venetian blind.
While it has heretofore been proposed to make such slats of PVC material, there have been subject to a number of disadvantages, those of which are directed to the method itself: manually apply glue ~adhesive material); need drying after gluing; and manually pressing. Therefore, resulting the following:
1. When apply ~lue on fabric, one layer of glue is not sufficient, another glue shall be applied on the substrate, i.e. PVC slat or like, to achieve bet~er result. Thus, material ~glue) consumption is wasted comparatively.
2. After apply glue, drying by means of a dryer becomes necessary in manufacture process, therefore, additional investment on drying facility is required.

3. Conventionally, dried slats need to be pressed to assure the slats being well-adhered. This step is carried manually tha~ results heavy labor investment.
4. ~hile process carr:ied out manually, it is easy to contaminate the surface of slate, in terms, the quality of product is decreased.
.3~3 StlMMARY OF TEIE INVENTION
The present invention discloses a method and apparatus of making slats enclosed by fabrics. It ultili~es feed rollers to slidably support said fabrics and slat produces located between two fabrics. Fabrics and slats are forced to move by rollers and power source mechanism; then are subject to a heat source to cause said fabrics and slats sticked together; furthermore, cool laminated slat by means of a cooling device and press said laminated slat.
Therefore, it is an object of the present invention to provide a method and apparatus to produce slats as set forth immediate above.
It is still an object of the present invention to save materials and laber work.
It is a further object of the present invention to eliminate contamination.
PREFERRED EMBODIMENT OF THE INVENTION
_____ _______________________________ Referring to Fig. 1 to 3, a method and apparatus of making venetian blind slats, whereas the slat is formed of a PVC base material 2, and fabrics 3. the method and apparatus according to the present invention comprises locating fabrics 3 on feed rollers 4 so that fabrics will follow each roller of said feed rollers 4, and PVC slats material 2 output from slats machine 5 so that said PVC slats materials 2 is positioned between said fabrics 2; compressing said fabrics and. PVC slat led by feed rollers 4 by heated rollers 6, whereas rollers 6 can be heated by either steam sprayed thereon or burning fuel therein; cooling laminated slats by cooling device 7, said blower in thi.s particular example;
pressing said laminated slats again to assure it being even on the surfaces.
It is noted that cooling device 8 can be the air cooling by said blower or any suitable means which will bring heat away from substrate (laminated slat).
It is further noted that the surface of fabrics 3 conta~ted with PVC slat 2 i~ treated to be rough so that when PVC is heated to slightly melt~ the roughed fabrics surfaces can stick thereon firmly.
~ O ~ J ~t'~
It may thus be seen that there has been provided a novel vene~ian blind slat construction which i9 to accomplish the objects set forth supra.
