Opening claim text (preview).
The invention claimed is: 1. An elongate web of wrapping material having a longitudinal axis and a series of U-shaped lines of weakening spaced from each other in a direction along the axis, each line of weakening being configured to form an extraction opening for the removal of smoking articles from a bundle of smoking articles wrapped in a longitudinal section of the wrapping material cut from the web, wherein each line of weakening comprises rounded ends spaced from each other in a direction transverse to the longitudinal axis, a portion of each line of weakening extending in a longitudinal direction, wherein each line of weakening is a continuous curve extending between said rounded ends, wherein no part of said continuous curve extending between said rounded ends is parallel to the longitudinal axis. 2. An elongate web of wrapping material according to claim 1 , formed from a laminate material. 3. An elongate web of wrapping material according to claim 2 , wherein each line of weakening of the series is formed in at least one layer of said laminate material. 4. An elongate web of wrapping material according to claim 3 , wherein each line of weakening of the series comprises a first line of weakening formed in one layer of said laminate material, and a second line of weakening formed in another layer of said laminate material. 5. An elongate web of wrapping material according to claim 4 , wherein the first line of weakening surrounds the second line of weakening. 6. An elongate web of wrapping material according to claim 1 , wound into a reel for mounting in a machine for wrapping bundles of tobacco industry products in said longitudinal sections cut from said web of wrapping material.
