Title:
【発明の名称】変形可能な材料のウエブを巻き付けるためのコア
Document Type and Number:
Japanese Patent JPH0729733
Kind Code:
B2
Abstract:
A core for winding a web of deformable material, such as photographic film base, which has knurlings along its margins. The core includes a rigid cylindrical member with a sleeve of resilient material. The sleeve has a cylindrical outer surface and has a length less than the distance between the margins containing the knurlings. There are means contiguous with the ends of the sleeves for providing cylindrical surfaces having diameters substantially equal to that of the sleeve. These means underlie the knurlings in the web when the web is wound on the core and may take the form of resilient material which is harder than the sleeve, or they may be rigid. In the latter case the surface-providing means may be integral with the rigid cylindrical member.
