In order to facilitate the installation of weatherstripping into channels, usually T-slots, of frames in windows and doors, variations in size of the slots is accommodated by changing the size of interference members extending from the backing strip of the weatherstripping. A forming tool, such as a shaft having a forming surface or on which a forming roller is movably mounted in a support structure. The support structure is disposed adjacent the mechanism of the insertion apparatus which feeds the weatherstrip into the T-slot of the frame. The support has a channel via which the weatherstrip passes into the insertion mechanism and thence into the T-slot in the frame. A wall in the support member presents the forming tool to the interference portions of the backing strip of the weatherstripping and is operative to swage and crimp or otherwise change the cross sectional size of the backing strip in relationship to the size of the T-slot which receives the backing strip. The forming tool is displaced so as to select the amount of crimping and enable as long a length of weatherstripping as is required to be installed in the frame without overloading and stalling the insertion mechanism. The size and disposition of the forming tool in the support may be selected to accommodate different styles of interference member on the backing strip. The installation apparatus is therefore universally adapted for various types of weatherstripping.
An apparatus for placement of a weatherstrip into a channel in a member from which a sealing portion of the weatherstrip extends from the channel outwardly of the member, said weatherstrip having portions which engage said channel to restrict movement of the weatherstrip when placed in the channel, the improvement comprising a forming tool, a support for said tool having a passage via which the weatherstrip passes into said placement apparatus, said forming tool being mounted in said support for movement toward and away from said portions for reforming said portions thereby selectively changing the size relationship between said channel and said portions and controlling the magnitude of restriction of movement of said weatherstrip in said channel engaged by said portions.
