Abstract

The invention concerns a stitched valve bag and a procedure for manufacturing stitched valve bags from a material web run in tubular form. The valve bag (30) is provided at both ends with a stitched seam (38), and the bag (30) has in one corner a valve member (34') constituting a valve opening. In the longitudinal direction of the mantle part (31) of the bag (30) has at one end (32) at a distance from the corner of the bag been made an incision (36) longitudinal to the mantle (31). The portion between the incision (36) and the corner has been folded to become a valve member (34'), along a folding line (35) extending substantially from the bottom of the incision (36) obliquely to the margin of the mantle part (31). On the side beyond the incision (36) the bag end (32) has for improved strength been folded double before stitching said end of the bag.

чтобы усилить клапанный конец мешка. Сгибанием углов клапанного элемента 4 по лини м сгиба 8 завершаетс  образование клапанного элемента. Сшивают торцы и производ т их загибание, а затем прошивание загнутых кромок. Формула изобретени to strengthen the valve end of the bag. By folding the corners of the valve member 4 along the fold line 8, the formation of the valve member is completed. Sew the ends and make them curled, and then flashing curved edges. Invention Formula Способ изготовлени  сшитых мешков с клапанами из полотна материала, заключающийс  в том, что полотно разрезают на заготовки, заготовку складывают , а с обоих ее торцов образуют сшивные швы, в одном из углов образуют клапанный элемент, загиба  угол к внутренней стороне, формирующий отверстие клапана, отличающийс  тем, что, с целью упрощени  процесса изготовлени  и экономии материала, после разрезани  полотна на заготовки, на одном из его концов на рассто нии вдоль кромки тррца от угла выполн ют надрез параллельно боковой кромке заготовки, а после загибани  углов клапанного элемента и сшивани  торцов производ т загибание торцовых сшитых кромок, которые затем прошивают.A method of manufacturing stitched bags with flaps from a web of material, which consists in cutting the web into blanks, folding the preform, and stitching seams at its both ends, forming a valve element in one of the corners, bending an angle to the inner side that forms the valve opening, characterized in that, in order to simplify the manufacturing process and save material, after cutting the web into blanks, at one of its ends, a cut is made parallel to the side edge of the billet And after folding the corners of the valve member and the ends of crosslinking tons is produced crosslinked bending of face edges, which are then sewn. f /f / Фиг.11 фиг.Зfig.Z J ItJ it 1one ::tl:: tl --г- y Фиг AFig a
