Title: Improvements in or relating to folding machines for flat bags and envelopes
IPC: B31B19/00
Filed: 1933-11-11
Abstract: 422,237. Machine for making paper bags and envelopes. GODER, M., 35, Adolf-Hitler-Strasse, Neuss, Germany. Nov. 11, 1933, No. 31509. [Class 94 (ii)] After the formation of the first two folds, the direction of feed of the blank for an envelope or flat bag is changed by 90‹ so that each fold is parallel to the folding roll by which it is made. Each blank 1 is drawn by a suction roll 5 so that it is folded about a line 67 between the roll 5 and a roll 7, has one edge 69 gummed by a gumming roll 9 and passes to a roller 14 supplied with compressed air. By this compressed air, the blank is blown against a stop 18 so that the edge 69 is caused to lead, and a projection 15 upon the roll 14 engages the edge 69 so that the blank is led between the rolls 14, 16 in position to make the second fold 70. The projection 15 is held outwardly by springs. Gum is applied to the usual closing flap 71 by rolls 27, 28, and the blank is fed by rolls 24, 25 to an endless band 38 moving at right angles to the previous path of the blank. The band 38 is moved at such a rate that the blanks are arranged thereon with the flaps 71 projecting so that the gum can dry before the final two folds are made. The blank passes from the band 38 to folding rollers 49, 50, immediately before which is disposed a folding knife 52 which creases the blank along a line 73. A gumming device 59 applies gum to the flap 72, while the blank is still held by the suction roll 50, and the blank is fed by the roll 50 to a folding spring 54 and stop 55. The fold 73 is formed between the roll 50 and spring 54. A mutilated roll 57 engages the flap 71 of the blank and feeds the folded blank beneath a guide 63 to a suction roll 64 by which it is piled upon a stack plate 66. In one modification, for forming envelopes in which the two side flaps are not stuck together, the rolls 5, 7, 9 are not employed, a suction roll is disposed above the roll 14, and the blank is drawn from a pile by the suction roll so as to form the first fold between the suction roll and the roll 14. With this form of apparatus a gumming device may be mounted upon the bracket supporting the pile of blanks, and the suction roll is gapped so that the blank may be folded without the gum adhering to the roll. In a second modification, the second folding may be performed by a folding spring and roller in the same way that the fold 73 is obtained, and the blank is fed from this folding device to the endless band 38 by a mutilated roll similar to roll 57.

Abstract: 245,104. Marcou, J. A. Dec. 20, 1924, [Convention date]. Belts; pulleys. - Belt gearing for connecting non-parallel shafts comprises a linked V-belt which is capable of limited flexibility at right angles to the planes of the pulleys and has friction faces inclined relatively at more than 45‹ and engaging corresponding faces on metal or leather covered pulleys. The belt and pulley may both be entirely of metal or one or both may have friction facings of light metals or non-oxidizable alloys, moulded or compressed material, leather, or in the case of the pulley, of wood. The belt friction members 1, Fig. 1, which are shaped in cross section as shown in Fig. 2 to engage a pulley, Fig. 11, are connected by links 2 freely pivoted on axes 8 at right angles to the belt length and of such elasticity as to permit lateral bending to an angle of about 2‹. An oil-tight flexible cover 4 surrounds each link. In the form shown in Figs. 5 and 7, connecting-links 11, 12 are rigid, but turn about pins 10 in the friction members 9 to an extent limited by stops 14, 15, free movement about the pulleys being permitted by the link-pins 13.

In an automatic voltage-control system for a separately-excited engine-driven aircraft alternator, the excitation is increased above normal full-load value if the alternator voltage drops due to overload. The exciter E has a selfexcited field Ef 1 , Ef 2  capable of producing a larger output than the normal full-load requirement of the alternator. The field Ef 1 , Ef 2  is divided into two parts and arranged at opposite sides of a bridge with resistors R1, R2 to voltage opposing the self-excitation is normally applied across one diagonal of the bridge by a magnetic amplifier MA2 so as to reduce the excitation to that required to maintain the alternator output voltage constant at the desired value. The alternator voltage is compared with a reference voltage CV to control a magnetic amplifier MA1 which in turn controls the amplifier MA2. An additional field winding Ef 3  aids the self-excitation and prevents polarity reversal which might otherwise occur if the output of amplifier MA2 were excessive.
