FREMGANGSMAATE OG INNRETNING FOR BELEGNING AV DE FIRE SIDEKANTER AV ET MULTIPPELVINDU

摘要

Apparatus for applying plastic material to the four edges of a multiple-pane window comprises first and second pairs of nozzles and first and second carriers for moving the window horizontally between the nozzles of each pair in succession. Transfer means, particularly a rotating column with a laterally extending arm, transfers the window from one carrier to the other and rotates the window to bring the edges uncoated at the first station in position for coating at the second station. The transfer device is advantageously correlated with the downstream limit of the first carrier and the upstream limit of the second carrier to transfer and rotate the window about its axis of symmetry. A function of the window length on the first carrier is measured and the separation of the nozzles of the second pair adjusted accordingly. A supply device centers a window and deposits it in a predetermined centered position in the first carrier. A downstream manipulator raises the windows to vertical positions, and a leading edge detector stops the second carrier when the leading edge of each window is a predetermined distance from the axis of rotation of the manipulator.
