Abstract
A device for applying adhesive applications on an addhesive transfer roller. The adhesive transfer roller delivers through a process of roling off its adhesive aplications to workpieces that are fed continuously for the purpose of gluing. To apply the formatted adhesive applicationm in a simple and clean manner on the transfer roller, there are, in addition to the transfer roller, adhesive nozzles that are spaced axially equidistant apart and are aimed against the jacket of the transfer roller. The adhesive application nozzles are provided with valves whose opening and closing times are controlled individually by a controller for the purpose of producing formatted adhesive applications.
Claims18
A device for applying formatted adhesive applications on a transfer roller, which delivers through a process of rolling off adhesive applications to workpieces or webs, fed continuously for gluing, which comprises a plurality of adhesive nozzles that are spaced axially equidistant apart and are aimed toward the transfer roller, said adhesive nozzles being provided with valves whose opening and closing times are controlled individually by a controller having a bit map storage for storing images of a plurality of formatted adhesive applications, said controller opening and closing said valves to apply adhesive according to a specific formatted adhesive application.
A device for applying formatted adhesive applications on a transfer roller which rolls off adhesive applications to workpieces or webs that are fed continuously along the transfer roller for gluing, which comprises a row of adhesive nozzles spaced axially and approximately equidistantly from one another and mounted on a support which moves said row of nozzles substantially parallel to a longitudinal axis of said transfer roller, said adhesive nozzles being aimed toward the transfer roller and being individually opened and closed by a controller.
A device for applying formatted adhesive applications on a transfer roller which rolls off adhesive applications to workpieces or webs that are fed continuously along the transfer roller for gluing, which comprises a row of adhesive nozzles aimed toward the transfer roller and spaced axially from one another at a distance which is at least twice a width of an adhesive track to be applied by each nozzle, said nozzles being individually opened and closed by a controller and being slid back and forth by the width of at least one adhesive track in time with one revolution of said transfer roller.
