Production — heavy-duty stapling machine
Many time-saving methods are employed in the making of war housing trailers at the Los Angeles plant of Western Trailer Company.
A heavy-duty stapling machine, for example, makes fast work of fastening the waterproof finish sheeting in place.
Later a decorative strip will cover the staple heads and the sheeting will be trimmed off flush with the lower edge of the strip.
