Abstract
The present invention relates to the art of continuous forming of elongated strip-like products made of thermoplastic material, and more specifically to apparatus and method to forming said thermoplastic material over a substantial portion of the circumference of a forming roll. The present invention is specifically related to the art of forming agricultural products, and especially for the production of drip irrigation strip which may be used for installing in the inner side of a tube or to be folded to form an irrigation tube.
Claims28
An apparatus usefull for a continuous processing of thermoplastic materials to form strip-like products having a predetermined shape and cross section, comprising;
- i. at least one forming roll,
- ii. at least one cooperated belt;
- wherein said apparatus comprising means to roll said cooperated belt adjacent to more than 20° of the outer circumference of said forming roll, so the inner circumference of said cooperated belt and tile said outer circumference of the forming belts are defining a gradually circular embossing lane;
- and so said thermoplastic material to be formed is passing longitudinally throughout said gradually circular embossing lane in the manner said strip-like product is obtained with the predetermined shape and cross section.
