One insert sheet is transferr to the gri pers 5 on the male folding cylinder 8 as tie grippers 5 and 12 are brought together. In the meantime the cutters 38 34, cut successive sheets from the cover web and feed the sheets between the guides 85, 36, into position to have the advance edge of each sheet engaged bv the grippers 14 on the transfer cylin er 13. (ma cover sheet is transferred to the grippers 7 of the female folding cylinder 4every revolution thereof when the ippers 7 and 14 are brought together. Tie rotary ,cutters 17, 18, which arev driven at twice the speed of the cutters for the insert and cover s ieets, sever sheets from the web fed from the truck roler128 aud a fixed cam 120 is ari-an edto control the insert tte'mainipress'fand feed them down between l guides I.10g'and'20.. The collecting cylinder19yis yarranged to have its grippers 10 collect two, sheets thereon and then transfer ythe'y two sheets to the rippers 5 on the male folding cylinder 8 wien the said grippors comete A ther.4 As the grippers 5 and ou the` two olding cylinders come together, the cover sheet on the female folding cylinder willbe transferred to the `male cylinder, thegrippers on the male cylinder then engaging the advance edge of one insert sheet,.two sheets from the main press and one cover sheet. Asthe foldin mechanism of thetwo cylinders 3^and 4 is rought into coaction, the grippers 5 are opened to release the advance edges of the collected group of sheets. The folded signature is then brought down between the tapes (i7, 68 and the Jaws 8 of the Vfolding mechanism are opened to permit the tapes 67. 68, to feed the folded signature between the slitters G9, 70, from whence the si atiires drop into the ockets in the carrier 71. The means for imparting successive movements to the pocket carrier to collect a series of folded signatures therein forms no part of the present.l invention and will therefore not be pecically described, it being understood iat the folded signature from the tapes may be slitinto t e r aired number of smaller signatures and t en deposited a't pro r intervals into the pocket carrier to pro uce the result desired.
It can be readil understood that instead of-transferring t e advance ed e of the cover sheet from the folding cylinder 4 to the folding c linder 8 to be combined with the insert an main web sheets thereon, the o ening of the grippers may be so timed tiifat the cover sheet. will not be transferred to the cylinder 3 but will be fed between the folding cylinders and have its advance edge released from the grippers 7 in ample time to permit the assembled insert, main web and cover sheets to be folded together and fed between the ta es 67, 68. It will be seen that t ie machine as hereinabove set forth accomplishes the assembling and folding together of sheets from the main press and from the insert and cover supplies without the necessity of employing formers, turning-bars or carrying tapes.
What I claim is:
1. Folding cylinders, a cylinder for trans` ferring one insert sheet at a time to one of the fo ding cylinders, a cylinder for delivei`- ing a plura ity of main web sheets at. a time to the said folding cylinder and a cylinder arranged to transfer cover sheets one at a time to the other folding cylinder.
2. Folding cylinders, a cylinder for transferrin; insert sheets one at. a time to one of the fo ding cylinders, a cylinder for delivering a plurality of main web sheets to said folding cylinder, a cylinder arranged to transfer cover sheets oneV at a, .time to the other folding 'cylinder' and means for foldtravel one revolution to one revolution of the folding Vcylinders and means for imparting variable surface speeds` to the insert sheet and cover Sheet transfer cylinders.l
