Title: Improvements in and relating to Machines for Applying Lace Paper Leaves or Flies to Paper Boxes.
Inventor: ALEXANDER ALBERT EDGAR
IPC: B31B3/74
Filed: 1918-02-04
Abstract: 121,846. Alexander, A. E., (Stokes & Smith Co.). Feb. 4, 1918. Pile supports for sheet feeds.-In a machine for applying paper leaves or flies to boxes, a stack F of the flies is supported on a cross-bar 75 and on a grid 76 extending therefrom, the bar 75 being slidable vertically in parts depending from an horizontally-sliding carriage. The bar 75 carries angle-blocks 79, a required number of which are placed in position between a plate 78 and the bar 75. A rod 81, carrying a spring that normally lifts the leaf support, extends through a bore in a slotted bar connecting the lower ends of the depending parts referred to. Front fingers 99 and guide-fingers 102 are mounted adjustably on the slotted bar, the fingers 99 having hooked ends overlying the edge of the stack; a removable slotted clamping-plate 105 overlies the stack. A rubber or other stencil 43 is clamped in a hanger 42 supported from arms 37, which are operated by lever mechanism &c. from suitable power mechanism in the lower part of the machine, the stencil being caused to rock forwards and downwards. In its descending movement, the stencil receives glue from a roller mounted to revolve in a glue tank on the horizontally-sliding carriage above referred to, this carriage being operated by lever mechanism &c., and the glueing-roller being rotated only during the forward movement of the carriage by reason of a one-way ratchet device in connexion with rack-and-pinion driving-gear; a small roller causes an even application of the glue to the glueing-roller. At a certain stage, a glued stencil contacts with the uppermost leaf or fly. and becoming retracted, partially lifts the front of the leaf, as shown, and the forward movement of the stack support brings this portion of the leaf against the face 123 of a stationary anvil 115. A box is placed on the anvil so that the interior of one of its side walls contacts with the edge of the fly or leaf on the face 123, and pressure is applied, to fasten the leaf, by a device comprising a rubber strip 125 on a bar 124 carried by suitably operated rock-arms. During the pressing operation, the leaf support is lowered by a friction gripping-device or by hand; but it is afterwards raised again. The mechanism for operating the stencil may be disconnected, to permit of operating the stencil by a handle-bar 40 when desired. The invention is an improvement on that described in Specification 7062/06.
