An apparatus for applying an adhesive spacer material to a substrate, such as a glass lite, for the manufacture of insulated windows. The apparatus 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 travelling applicator head is adapted to move transversely across the conveyor, rotationally through 180.degree., and vertically above the substrate. 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 in the spacer material and rotating 90.degree. at the corners of the substrate. The stationary applicator head applies spacer material to the fourth side of the substrate. The apparatus provides the mechanism necessary to produce tight accurate corners, including a punch for notching the spacer material in the corner area, and cooperating pairs of grippers for forming accurate fold placement of the spacer material at the corners. The traveling head has a lead gripper and a lag gripper, each is of a pair of grippers. The grippers form an application channel for positioning the spacer material on the substrate, and the grippers are mounted for pivotal movement relative to the other.

[ I claim:] [1.] A traveling applicator head for applying adhesive spacer material to a substrate in a spacer application station in the production of insulated windows, comprising:a traveler for supporting the applicator head at a distance from the substrate;a drive means for selective transverse reciprocating movement of the traveler and the applicator head;a central housing rotatively supporting the applicator head on the traveler;a lead gripper comprising a pair of lead gripper members defining a first channel therebetween;a lag gripper comprising a pair of lag gripper members defining a second channel therebetween, at least one of said lag gripper and said lead gripper being mounted for pivotal movement relative to the other of said lead gripper and said lag gripper, defining in combination with the lead gripper an application channel for positioning the spacer material on the substrate.
