Abstract:

A relatively small, portable rotary heat sealer which may be held by a hand to support it during operation including a frame, and first and second wheels mounted on the frame. The wheels are rotatable with respect to the frame about respective first and second axes which are generally parallel to each other. Both wheels have rims, with the rim of the second wheel positioned adjacent the rim of the first wheel to define a nip for receiving heat sealable material. An electric motor rotates the second wheel about the second axis such that the heat sealable material is drawn into and through the nip. The rim of the first wheel is heated so that the material is sealed as it is drawn through the nip. A handle is affixed to the frame for carrying the rotary heat sealer and for supporting the heat sealer during its operation.
