Patent ID: 8267141

Claim:
An apparatus for manufacturing a heat insulator, the apparatus comprising: a frame having a feeder provided at front side of the frame for feeding a cross-linked foam polyethylene sheet and a winder provided at rear side of the frame for winding a completed heat insulator; a cutting part provided at a leading side of the frame, which is for forming multiple cutoff slots in the cross-linked foam polyethylene sheet fed from the feeder; a widening part provided at a rear side of the cutting part, which is for transforming the cutoff slots into cells by widening a width of the cross-linked foam polyethylene sheet formed with the cutoff slots; a cooling part provided at a rear side of the widening part, which has cooling rollers to continuously maintain a widened width of the cross-linked foam polyethylene sheet and a shape of the cells transformed from the cutoff slots; and a sheet-attaching part provided at a rear side of the cooling part, which is for attaching an aluminum film on at least one surface of the widened cross-linked foam polyethylene sheet formed with the cells so as to show high reflectivity and low emissivity.
