The difference between a heat shoe and heated roller lies in how heat is applied to the laminating film. With a heat shoe laminator, the laminating film is pulled across curved pieces of Teflon-coated metal (the heat shoes) before it enters the nip, the place where the laminating rollers meet. The rollers simply apply the pressure to squeeze the adhesive onto the item being laminated. The rollers become hot as a result of heat radiating from the heat shoes like a rotisserie. This can cause the back side of the rollers to remain cooler than the front of the rollers until the laminating rollers have been turning for a sufficient period of time.
With a heated roller laminator, the silicon rollers are internally heated and provide both the heat and pressure to laminate simultaneously.
