Abstract
Abstract A device for controlling the glue nozzles of a machine for gluing together at least two paper webs provided with recurring form designs to produce multi-part sets of continuous forms. The control device has at least one sensing element and at least one glue nozzle which are both connected to a computer. Also connected to the computer is a displacement transducer for determining the position of the beginning of a form with respect to the respective glue nozzle. In a "read-in" mode, the sensing elements senses a specially treated read-in form, and the values obtained are stored in the computer. In a second mode, the "glue" mode, the computer activates the glue nozzles precisely when the displacement transducer provides an address for which a "glue" instruction was stored during read-in.
