Weatherstripping is inserted in an extrusion on-line with an extruder which provides the extrusion as it moves towards a station. The extrusion at such station is pulled and cut into sections from which frames of windows are fabricated by fabricators, thereby avoiding the need for insertion of the weatherstrip into the sections offline by the window fabricator. The insertion apparatus includes rollers and an insertion wheel which inserts the weatherstrip into a slot on one side of the extrusion. Rotation of the rollers is coupled to the insertion wheel by a transmission so that the weatherstripping is driven at the same or greater lineal speed than the speed at which the extrusion moves towards the pulling and cutting station, thereby assuring that the weatherstrip reaches the cutter in the cutting station simultaneously with or ahead of the extrusion at the cutter and is not pulled back, which would be the case if the insertion wheel was not rotationally coupled to the rollers and moved at a slower speed than the extrusion due to friction which retards the rotation of the wheel. The sections are filled with weatherstripping along their entire length to facilitate the use thereof by the fabricator in providing components of the frames of the windows being fabricated.
