An apparatus for applying an adhesive spacer material to a substrate such as a glass lite for the manufacture of insulated windows includes an infeed and an outfeed conveyor for advancing a glass lite, and a transverse beam on which is mounted a first travelling applicator head and a second stationary applicator head. A first and second feed reel are provided to supply spacer material to their respective applicator heads. The stationary applicator head is adapted to apply a length of spacer material in a straight pattern simultaneously with the travelling head as the substrate is advanced by the conveyor. The travelling applicator head applies spacer material to three sides of the substrate cutting notches or slits and rotating 90.degree. at the corners. The stationary applicator head applies spacer to the fourth side. Cooperating pairs of grippers form accurate folds in the spacer. The apparatus is intended to automatically apply spacer material to glass lite assemblies suitable for in-line production, permitting the fabrication of high volume of insulated glass assemblies with a low level of manual intervention.

1. An apparatus for applying adhesive spacer material to a substrate, comprising:a support means for supporting the substrate; a beam oriented transversely to the support means; at least one travelling applicator head for applying spacer material to the substrate supported on the beam spaced from the substrate; at least one feed reel for supplying spacer material to the at least one travelling applicator head; means for advancing the at least one travelling applicator head relative to the substrate; wherein the at least one applicator head includes:drive means for providing reciprocal movement of the at least one applicator head on the beam; a central housing secured to the drive means about which the at least one applicator head is rotatable; a lead gripper and a lag gripper mounted to the central housing defining an application channel for receiving the spacer material and applying it to the substrate, said lead and lag grippers each comprising spaced apart gripper members, at least one of said lead and lag grippers being mounted for pivotal movement relative to the other of said grippers.
