Abstract
An installation machine for sequentially driving fasteners through automatically fed plates for securing insulation to a roof deck employs a pneumatically actuated feed mechanism. The plates are loaded in a chute. A shuttle at the underside of the frame reciprocates to feed a plate in position below a power driver for driving the fastener through the fastener plate. The frame includes a pair of wheels for facilitating the movement of the machine across the roof surface. A pneumatic regulator responsive to release of the power driver regulates the timing of the feed mechanism.
