CORE FOR A PRODUCT IN SHEET FORM WOUND AROUND THIS CORE, AND ROLL FORMED WITH SUCH A CORE |
摘要 |
A core has a cylindrical wall that can be torn axially and is made up of two superposed strips, these strips respectively being an outer strip in contact with the product and an inner strip, these strips being wound on one another and joined together by regions of attachment for example by bonding. At least one of the longitudinal edges of the inner strip is not attached or is weakly attached over a determined width in order, over at least part of its helical length, to form a free and accessible tab facing the outer strip. |
