Title:
ROLLING UNIT FOR URETHANE FOAM TAPE
Document Type and Number:
Japanese Patent JPH06298416
Kind Code:
A
Abstract:

PURPOSE: To provide a rolling unit for an urethane foam tape, which has smooth both end surfaces, makes the width uniform, avoids any line trouble at the time of using, and is excellent in beauty.

CONSTITUTION: A main rolling unit comprises a cylindrical core part 1 (foamed polystyrene, foamed polyethylene, cork or the like), an urethane foam tape winding part 11 where an urethane foam tape having a width corresponding to the height of the cylindrical core part is wound several times over while tension is applied thereto, wherein both end surfaces of the urethane foam tape winding part 12 are sections, and the maximum height difference of the projecting and recessed surface in an arbitrary pitch width 50mm in the radial direction of both end surfaces is 1mm or less. The urethane foam tape is wound in such a manner that the length of the wound urethane foam tape (apparent specific gravity in the case where the rolling unit has the same diameter) is 1.15 to 2.0 times as long s the length (260m) of the urethane foam tape before winding, with tension applied thereto.
