Abstract
An apparatus for producing foam-filled stud walls. The apparatus has a main frame, including a substantially vertical backplate against which the sheathing bears, a carrier unit moveable vertically on the main frame, and a dam carried on the carrier unit parallel to the backplate, moveable towards and away from the backplate. Hydraulic actuators are located between the carrier unit and main frame, and between the dam and the carrier unit, to hold the dam against the stud wall when the stud wall is positioned with its sheathing against the backplate, and to move the carrier unit and thus the dam vertically while it is so held against the stud wall.
