Abstract
The gluing apparatus has several carrier arms attached to a rotating organ, which carry holders at their free ends. Each holder picks up an attachment slip at the supply point, transports it past an adhesive-applicator apparatus whereby adhesive is applied to the attachment slips, and on to the printed products to which the slips are then attached. The printed products are transported on supports placed perpendicular to the feed direction (A), the holders enter between consecutive pairs of supports and have means of control to move them against supports, in order to glue the attachment slips on the printed products and press them firmly into place.
Claims15
Apparatus for gluing attachment slips to printed products comprising:
- rotary means for transporting printed products in a feed direction (A) and having supporting elements extending traverse to the direction (A) and arranged one behind the other at intervals and on which the printed products are supported in close contact;
- and a gluing apparatus including an adhesive applicator and means for transporting an attachment slip from a supply point past the adhesive applicator and thence to the printed product for pressing the attachment slip onto the printed product on a supporting element of the rotary means, the means for transporting and pressing including a rotating organ, several carrier arms projecting as cantilevers from the rotating organ and arranged one behind the other at intervals in the direction of rotation (B) of the organ, each of the carrier arms having a holder driven to rotate along a fixed path to pick up an attachment slip at the supply point, the rotating organ and carrier arms being designed to introduce the holders between consecutive support elements and control means to move the holders toward a corresponding support element and press the support element with the glued attachment slip on to the printed product supported on a supporting element.
Apparatus in accordance with claim 16, wherein the holders have elastic suction heads that can be connected via a controlled valve layout to the source of a partial vacuum in order to hold the attachment slips from the supply point until they have been pressed into place.
