Abstract

760,449. Making valve-bags. RAWE, M. Sept. 3, 1954 [Nov. 17, 1953], No. 25648/54. Class 94(2). A bag-making machine is provided with a device for ensuring the correct position of valve inserts, comprising holding means for the valve insert which are moved with the bag in synchronization with the bag conveying means. As shown, inserts 2 are fed on a roll 1 to the bottom of a bag fed in the direction 3. A chain 9 carried by sprockets 5, 6. 7, 8, mounted on a member 4, and carrying pairs of holding pins 10 on each link, is driven through the shaft 22, the member 4 being pivotally mounted at 22 on an arm 12 adjustable about a fixed shaft 13 by means of a clamping screw 14. In operation the pins 10 pierce the bag bottom and the valve insert during the closing of the bag bottom. The member 4 may be lifted out of the operating position and supported by a spring-loaded arm 17.
