Definitions

  • the blanks normally traveling through the machine in spaced-apart relation at very high speeds, are reduced in speed without reducing the succession rate. This causes the blanks to decrease in spacing, even to the degree that they overlap, but such overlapping is limited to the extent that the covering or upper flap of the adjacent blank does not overlay the area of the panel to which patch gum is applied.
  • the ' patch gum may then be applied by suitable, known, relatively low speed apparatus, after which the patch may be applied, preferably at the same reduced surface speed. Subsequently, the blanks may be further decreased in spacing for additional operations such as seal flap gumming, or decollated with attendant acceleration for normal high speed operations such as scoring and folding.
  • FIG. 2 is a diagrammatic illustration showing successive steps involved in operating upon envelope blanks in accordance with this invention.
  • the reference numeral 1 generally indicates patch applying apparatus embodying this invention for use in conjuiction with high speed rotary envelope making machines.
  • the apparatus 1 is adapted to receive and convey a progression of pre-cut or web cut envelope blanks 2 therethrough with each of the blanks having a forwardly directed flap portion 3, a rewardly directed flap portion 4 and a panel portion 5 therebetween.
  • the panel portion 5 has a Window opening 6 pre-cut therethrough.
  • the envelope blanks 2 are conveyed through the apparatus 1 along a path designated 7 during which several operations are performed thereon as noted below.
  • the blanks 2 are fed into the apparatus 1 in succession at a relatively high surface speed and in spaced-apart relation by known devices, in this example, illustrated by a vacuum gripping cylinder 8.
  • the gripping cylinder 8 is suitably adapted by conventional valve structure (not shown) to permit transfer of the blanks at the high surface speed and spaced-apart relation to a vacuum gripping cylinder 9 forming part of a device 10 adapted to reduce the blank spacing, in this example to the extent that a squamiform lapping of the blanks is produced.
  • the device 10, in this example is-of the type disclosed in US. Pat. No.
  • a blank 2 is released from the face 12 by shut-01f of the suction when a leading edge of the blank reaches the bight between the rollers 14 and- 17, so that these latter rollers take over the advancing of the blank at a slower speed.
  • the trailing portion thereof is raised by a blast of air from a nozzle 23 to permit the following blank, which is maintained against the gripping cylinder 9, to run under the raised portion of the preceding blank, thus producing the desired overlap depending upon the relative peripheral speeds of the gripping cylinder 9 and braking rollers 14.
  • This apparatus includes a feeding mechanism 38 for feeding a web of patch material 39 to a cut-off mechanism 40 for cutting individual patches 41.
  • a transfer mechanism 42 in the form of a vacuum gripping cylinder, is adapted to receive the cut patches from the mechanism 40* and transfer same to the gripping roller 36 from which the patch is applied over the window opening 6 and on the gum pattern 34 with the impression roller 32 serving as backing.
  • the respective vacuum port 33 is deactivated permitting the blank leading edge to be received between rollers 43 from which it is directed into a suitable conveyor 44 for transfer into other sections of the envelope machine where additional operations are performed for producing a finished envelope.
  • Apparauts for applying patches to a progression of moving envelope blanks each having a forwardly and a rearwardly directed flap portion and a patch receiving panel portion therebetween, said blanks moving along a path at high surface speed and in spaced-apart relation, said apparatus comprising:
  • a speed reducing device located along said path and including one gripping transfer member and one pair of bight forming members, said gripping transfer member receiving said blanks at said high surface speed and in said spaced-apart relation and being positioned for feeding said blanks between said pair of bight forming members, said bight forming members operating at a predetermined lower surface speed than said gripping transfer member whereupon the surface speed and spacing of said blanks along said path is reduced only to the extent that said panel portion remains uncovered by adjacent blanks sufrficiently to permit exposure of a patch receiving area thereon but the rate of blank succession is not reduced,
  • said gripping transfer member includes a vacuum gripping cylinder and said bight forming members include contacting braking rollers.
  • said forwarding members include an impression roller receiving and driving said blanks along said path at said reduced speed and spacing,
  • impression roller being adapted to support said blanks during said gum application and said patch application.
