WOVEN PLASTIC BAG AND METHOD OF MAKING SAME

摘要

A woven plastic bag is made by longitudinally feeding flat-lying fabric web having a layer of woven-together plastic strips on a first face, opposite longitudinal edge regions spaced transversely from each other and each extending over about 10% of a transverse width of the fabric web, and a middle section between the longitudinal edge regions. A pattern is applied the first face of the fabric web in a pattern that repeats along the production direction only locally with a coating in the form of a film or in the form of a liquid plastic of a width or shape that varies transversely, and the fabric web is shaped into a fabric tube. In order to form individual woven plastic bags, the fabric tube is cut transversely into pieces of the fabric tube suitable for subsequent filling and sealing.

1. A method of making a woven plastic bag, the method comprising the steps of:
feeding in a longitudinal production direction a flat-lying fabric web having a layer of woven-together plastic strips on a first face, opposite longitudinal edge regions spaced from each other perpendicular to the production direction along a transverse direction and each extending over about 10% of a transverse width of the fabric web, and a middle section between the longitudinal edge regions; applying to the first face of the fabric web a pattern that repeats along the production direction only locally with a coating in the form of a film or in the form of a liquid plastic of a width or shape that varies in a transverse direction; shaping the fabric web into a fabric tube; and, in order to form individual woven plastic bags, cutting the fabric tube transversely into pieces of the fabric tube suitable for subsequent filling and sealing.
