Devices for forming paper bags or the like with flat rectangular bottoms are known 1n which a former is used which grips a paper 0 the bag on each side wall of the former whereupon further folders press in the bottom flaps and finally the remaining sides which are coated if desired with adhesive are formed by folders applied to the bag on the former.
- Since in devices of this kind the folders have been formed as flaps operated by the former rapid operation is not possible while unsatisfactory work was produced due to the sensitiveness of the flaps acting under du lex springs.
s distinguished therefrom the present invention resides in this that in the sha ing channel rollers provided on the' perip cry with wedge shaped-grooves are freely rotatably mounted at two opposite side walls of. the former in such manner that they roll along the moving former the edges of which en age the wedge shaped grooves in the rol ers.
In accordance with the invention also, the rollers drawn by springs into their position of rest on their profiled parts bearing on the side walls are provided with notches or recesses which are so disposed with respect to the arriving former that the bottom portion enters the recesses or notches and the folding of the side walls commences only later when the former has set the rollers in motion by means of projections mounted on the rollers. The shaped rollers co-operating with the former rest on the corresponding side walls of the former and are entrained by friction; The still projecting sides can then be; turned over by means of known folders or rails.

BAGS OR CARDBOARD BOXES 372,19),- and in Germany June 26, 1928.
The invention is illustrated inthe accom panying drawing in which Fig. 1 is a side elevation, Fig. 2 a front elevation and Fig. 3 a horizontal section on the line 3-3 of Fig. 2. Figs. 4 and 5 show to enlarged scale the conditions. Figsufi, 7 and 8 show to enlarged scale the co-operation of the rollers with the shaping member.
The principal parts of the device are as follows he former or die 1, the shaping channel 2 in which the former operates, the two rollers 4; and 5 formed with wedge shaped grooves 3, the rails or bars 6 and 7, and the ejector 8. 1
Referring to the drawing, the rectangular blanks 2 are brought by sultable means (not the plates 9 and 10 in front of the opening 11 of the shaping channel 2. The
former 1 is now moved downwards and passes with the blankinto the shaping channel, the side walls of the bag being thus formed The former then passes to the rollers 4 and 5, the edges of the blank projecting beyond the formerentering the 'notches12 in the rollers/L and 5 (Fig. 6 At the same time the front wall of the ormer 1 strikes against the projections 13 on the rollers which are thus set in rotation (Fig. 7) and roll along two edges of. the moving former. As the result the two side walls 8' are folded on the former (Fig. 8). While now the former moves forwards the two sides b are folded by the rails orbars 6. The sides .9 in upright position move past the rails 6 the gaps 14 and are then folded by the ralls 7 Whenthe former hasreached the end of its stroke resilient strippers 15 engage hind the bag and retain it when the former moves upwards again. The ejector 8 then ejects the completed ha or box into a pile Efter the former has moved out of the shaping channel the rollers 4, 5 are rotated backwards by springs 17 until the pro ections 18 on the rollers strike 50 I: in ,rotation.
I tio n*wit :Llgshape, folding-.means acting to form two sides and .the bottom and means for pressing The operation can then be rep The stops 18 and 19.permit therollers 4 and 5 to make only a single revolution. The diameter of the rollers must therefore be such'that on rolling along the edges of the former they need only make one revolution. Before the blanks enter the device the'yare suitably coated on their side and bottom portions with adhesive. This operation can be known manner by gluing carried' out in rollers.
