Claims
- 1. A method of manufacturing a roller having a corrosion-free outer metal working surface for use in the manufacture of paper, cardboard, or the like, comprising the steps of:
- a. forming a plurality of sleeves of a corrosion-free metal, each sleeve having a plurality of annular grooves on the exterior surface thereof; and
- b. mounting said sleeves axially adjacent to one another on a cylindrical metal core by heating said sleeves prior to mounting and sequentially heat shrinking said sleeves onto said core.
- 2. The invention according to claim 1 and further including:
- a. forming a plurality of thin intermediate sleeves of substantially the same width as said corrosion-free sleeves;
- b. sequentially placing said thin sleeves on said core prior to heat shrinking said corrosion-free sleeves in a manner such that an intermediate layer covers width extending from the corrosion-free sleeve last shrunk on, which width is at least equal to the width of one corrosion-free sleeve but not as great as the width of two corrosion-free sleeves; and
- c. mounting said corrosion-free sleeves from the side of said core to which said intermediate sleeves have not yet been mounted, whereby said heated corrosion-free sleeves will have substantial tolerance with respect to said core until just prior to reaching their proper position adjacent to a previously mounted corrosion-free sleeve.
- 3. The invention according to claim 2 and further including:
- a. forming at least a first and a second plurality of thin intermediate sleeves of width substantially equal to the width of said corrosion-free sleeves;
- b. sequentially placing ones of said first and second plurality of intermediate sleeves over said core to form first and second intermediate layers prior to heat shrinking said corrosion-free sleeves in place with:
- 1. said first layer placed directly over said core and having a width extending from the last mounted corrosion-free sleeve which is greater than the width of one sleeve but not greater than the width of two sleeves; and
- 2. said second layer placed over said first layer and having a width greater than one sleeve width but less than the width of said first layer so that the edges of the sleeves in said first and second layers are axially displaced from each other.
