Filed: 1929-07-29
Abstract: 337,387. Triggs, W. W., (Cornell Multi- Wall Valve Bag Co.). July 29, 1929. Paper bags.-A blockbottom for a multi-ply bag or bag tube is formed by folding in and securing a group of plies in one side flap between plies of the other side flap. The usual folding of the flattened tube produces end flaps 14, 15 and side flaps 12, 13, the outer ply of the tube being lowermost in the flap 12 and uppermost in the end flaps 14, 15. This ply is cut along the edge or fold 21 as far as the line 18, about which the flap is to be inwardly folded and the four uppermost plies are folded inwards together, the opposite side flap 13 is folded down on to them and finally the lowermost ply of the flap 12 is folded down on the flap 13 to complete the bottom, the parts being adhesively secured together. To strengthen the adhesion, the upper-, most ply of the end flaps is cut away as at 23 to permit the ply 24 exposed beneath it to be secured to the remaining top surface of the end flaps 14, 15. The folding may be facilitated by notching the plies as at 30, 31, or by providing all the plies with notches of varying size and position. In a modified form, cuts parallel to the axis of the bag tube, provide straight edges 80, 81, Fig. 7, between the side and end flaps and the cut in one ply is continued to the folding line to produce a single ply outer flap 85 and multi-ply inner flap 84, the separated triangular flaps 86 being folded down with the inner flap 84. Reference has been directed by the Comptroller to Specifications 318,968 and 337,517.

Abstract: 498,067. Cigarette making and like machines. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. Sept. 2, 1937, No. 24014. [Class 130] Tobacco is fed to mechanism for forming a continuous tobacco filler by moving a number of trough-like receptacles transversely of their length in succession beneath a shower of tobacco whose width extends along the length of the receptacles and whose length extends in the direction of movement of the receptacles, the tobacco being showered at such a rate that a receptacle contains a substantially uniform strip of tobacco after passing along the length of the shower and receiving tobacco from successive points along the shower, and directing the strips of tobacco so formed towards the filler forming mechanism without subjecting the strips to a final picking. In the apparatus shown, the receptacles 18 are formed by angle elements 20 secured to the periphery of a roller 21 intermittently rotated by camactuated pawl mechanism comprising a feed pawl 39 and a locking pawl 40. The receptacles receive tobacco showered by a picker roller 17 from a carded feed roller 13, and any tendency of tobacco shreds to lodge on the tops of the elements 20 is prevented by rapidly rotating rollers 22. The strips are retained in the receptacles by a moving endless band 25 until they are delivered to a conveyer 23, which moves continuously in a trough 24 and may comprise an endless band or a web of cigarette paper. The relative speeds of the roller 21. and the conveyer 23 are preferably such that, during the time in which a point on the conveyer moves a distance equal to the length of the receptacles, four strips are delivered to the conveyer. An intercepting device between the roller 21 and the conveyer comprises a stationary wall 27 and a movable wall 29 operated in timed relation to the roller by a cam 34 acting through a lever 32 and link 31.
