| 20110177268 | FILM OF PLASTICS MATERIAL STRETCHED TO PRESENT A PRIVILEGED SHRINKAGE ORIENTATION, A HEAT-SHRINK SLEEVE MADE OUT OF THE FILM, AND AN ARTICLE COVERED IN SUCH A SLEEVE - The invention relates to a film of plastics material stretched to present a privileged shrinkage orientation and used in particular for fabricating heat-shrink sleeves, the film including at least one line of mechanical weakness and at least one local region of extra thickness extending along the line of weakness so as to border it, the line of weakness and the adjacent local region of extra thickness together defining a tear line. According to the invention, the local region of extra thickness is constituted by applying liquid or semi-liquid material to the film, the applied material being applied to the film in a quantity that depends on the expected shrinkage ratio in the portion of the film that includes the tear line while a sleeve made using such a film is being heat-shrunk onto an article. | 07-21-2011 |
| 20100037556 | DEVICE FOR PLACING SLEEVES ON TRAVELING ARTICLES - The invention relates to a device for placing sleeves on traveling articles, said sleeves being cut from a continuous sheath passing over a sheath-opening shaper, first outer wheels serving to advance the sheath along the shaper, and second outer wheels being provided downstream from cutter means for the purpose of ejecting the cut-off sheath segment, said wheels being driven in rotation by associated electric motors controlled synchronously by a virtual-shaft common electronic programmer. In accordance with the invention, the programmer is arranged to determine a continuous profile of speed variation for the associated electric motors, said profiles being bell-shaped and having a common end segment in which the profiles coincide, this corresponding to the motors having identical speeds, the length of the common end segment being selected so that the sheath is advanced beyond the point of tangential contact with the second wheels so that said sheath is pinched by said second wheels prior to being held stationary for the cutting and ejection pass. | 02-18-2010 |
