Abstract

The invention relates to a method for producing and filling bags of produce using a supply of very long tubular netting. The invention includes: a loading phase, in which a segment of tubular net is positioned on a loading tube, such that the long end portion of the tubular net that encircles the tube is gathered, pleated and compressed longitudinally and such that a second short intermediate portion of the tubular net is stretched out, without gathering, and in which a loading hole is made in the stretched intermediate portion of the tubular net; and a production and filling phase, in which successive segments of the long gathered end portion of the tubular net are repeatedly stretched so that these segments ca be manipulated to form individual bags, the produce to be stored being inserted into each bag through the loading hole made in the stretched short intermediate portion of the tubular net.

Dependent claims

A process for manufacturing bags and filling them with products, such as fruit and vegetable products, from a storage of tubular net with great length, comprising

a loading phase, comprising the operations of arranging a section of tubular net on a loading tube, having its ends at a different height, until said loading tube is longitudinally introduced inside the mentioned section of tubular net and such that a long end portion of the tubular net which tightly encircles the loading tube is gathered and compacted in the longitudinal direction and that a second short intermediate portion of the tubular net which tightly encircles the loading tube is drawn without being gathered;
and of making a loading opening in the drawn short intermediate portion of the tubular net by means of cutting;
and
a manufacturing and filling phase, comprising the repeated operation of drawing successive sections of the gathered long end portion of the tubular net for the handling thereof in the manufacture of respective bags, introducing the products to be stored in each bag through the same loading opening made in the drawn short intermediate portion of the tubular net, the products falling by gravity through the loading tube until reaching the section of tubular net of the bag in the course of manufacture and being deposited therein.

1 more element

A machine for manufacturing bags and filling them with products, such as fruit and vegetable products, from a storage of tubular net with great length, comprising a loading tube intended to be longitudinally introduced in the tubular net and a support structure for drive means for driving the tubular net outside the loading tube and for cutting means for cutting the mentioned tubular net, wherein the loading tube is provided with a side opening and with at least one transverse support roller, rotating about a shaft integral with the loading tube;

and in that the drive means comprise at least two transverse and parallel rollers, applied on opposite faces of the loading tube, with the interposition of the tubular net during the operation of the machine, between which the loading tube is guided and on one of which its transverse support roller rests, the loading tube suspended from the support structure being prevented from moving in the downward direction, the loading tube being provided below the side opening with a lower portion with enough length so that a long end portion of the tubular net, gathered and compacted in the longitudinal direction, can tightly encircle it, enough net for the manufacture of more than one bag being accumulated on the lower portion.
