Abstract: A heating roller device is used to fix a film to a sheet in a laminator, and has two heating rollers. Each of the rollers includes a hollow support shaft, a roller body disposed rotatably around the support shaft, and a heating element disposed in the roller body. An electrical wire extends into the support shaft, and is in electrical connection with the heating element.

Abstract: An electrical heating wire assembly includes a heating wire with a bundle of electrical heating filaments, a conductive wire, and a connector interconnecting the heating wire and the conductive wire. The connector includes a conductive body that has a block portion formed with a recess which receives and which is electrically connected to the conductive wire, and a pin portion that projects from the block portion into the heating wire to contact the heating filaments. An insulator watertight sleeve is sleeved on the conductive body and ends of the heating wire and the conductive wire, with the pin portion extending outwardly through a terminating end of the sleeve. With the construction as such, heat at ends of the heating filaments, which are surrounded by the sleeve, is negligible.
