Abstract: A tape applicator for application of a double-sided adhesive tape to a member which can be cut and assembled to form a frame or sash for glazing for a skylight, a window or a door, or which can be used to form a muntin. The tape applicator includes a drive roller for advancing members sequentially through the apparatus. The tape applicator also includes a pressure roller for urging the tape onto the member, and for urging the member into engagement with the drive roller. A guide roller guides the location of the tape to the member so that it is applied to the proper location. A cutting mechanism is automatically actuated for cutting the tape adjacent the trailing end of each member at a desired location. The cutting mechanism is actuated by a switch which is engaged by the member.
