Abstract:
1. An apparatus for covering a cylindrical roll core with an elastomeric material, the roll core having a longitudinal axis of rotation and an outer surface for receiving said elastomeric material thereon, the apparatus comprising: a pair of opposed vertically aligned rotatable chuck means for receiving and securing said roll core therebetween for rotation of said roll core about its longitudinal axis, said chuck means holding said roll core vertically stationary; means for dispensing and helically winding a length of flexible tape around said roll core from the bottom to the top thereof in spaced apart relation to said roll core's outer surface to form a containment sheath defining an annular space between said outer surface and said tape, said tape being wound in response to rotation of said roll core by said chuck means; discharge means for discharging said elastomeric material into said annular space concurrently with said space's formation as said flexible tape is wound around said roll core; support means for said means for dispensing and said discharge means for vertical movement thereof relative to said roll core; and motor driven means for controllably moving said support means up and down relative to said roll core.
