Abstract: An enhanced plastic net bag is provided and is configured to be used for the commercialization of food products. The bag has a longitudinal axis and at least one end. The bag includes a tubular mesh body fabricated at least partially of plastic material; and at least one laminar strip having at least one end. A closure is formed by an enveloping association between the at least one end of the tubular mesh body and the at least one end of the laminar strip by laying the laminar strip over the tubular mesh body and folding both the laminar strip and the tubular mesh body. The laminar strip is heat sealed to the tubular mesh body to form at least one heat weld wherein the at least one heat weld is transverse to the longitudinal axis. The at least one heat weld comprises a fused mass comprising at least two layers of the laminar strip and at least two layers of the tubular mesh body.

Abstract: Automatic scale for bulk products with a feeder mechanism composed of two sets of turning transverse eccentric rollers, with both sets having parallel eccentrics, which are smooth in one set and notched in the other set. The transfer mechanisms have pairs of discs with parallel transverse shafts, with the outside ones having a pin meshed in a fixed toothed wheel, while the central shafts are mounted ungeared. The linear transport mechanisms have rods for supporting the containers with pairs of sliding mechanisms, which are separated by elastic mechanisms and have control mechanisms for varying their distance apart. The weigh station has pairs of parallel, longitudinal endless belts.

Abstract: A machine for manufacturing, filling, and closing bags of meshed fabric, from a continuous roll of meshed fabric of the type which manufactures inverted bags comprised of a portion of tubular meshed fabric closed at the top by a sheet folded over itself, which includes a first station for feeding the meshed fabric provided with first pressing members, second pressing members and cutting means; a second feeding station of the thermoweld sheet, which is to comprise the closure of the mouth of the bag, provided with a feeder device of the sheet; means of folding the sheet, means of welding the sheet; means for applying said sheet, and means of cutting the sheet; a third station for filling the bag in inverted position, provided with adjustable cams for separating the second pressing members, lower means of support for the bag, and means of filling the bag; and a fourth station for tying a belt string, closing the bottom of the bag, and unloading the filled and sealed bag, provided with a device for tying a belt

Abstract: Improvements in the object of the U.S. Pat. No. 5,294,283 for an automatic labelling machine for packers in bags of mesh or the like, which have: a second roller (101) with its counter roller (102), some independent means of activation (120), (121), and (123) of the means of cutting (16), of the cart (18), and of the finger (27) with claws (28); the printer head (10) and the counter roller (102) both being mounted on elastic laminar supports (112) and (104), with keying in their respective operating position; and mechanical linkage of turning (127) and (128) of the second roller (101) and of the roller (6).
