  • Patent number: 11098753
    Abstract: An end piece suitable for forming a spacer for a roll having two concentric tubes with axis, including spokes connecting two inner and outer cylindrical portions, and is where a fluid circuit originating from the center towards the periphery includes a first circumferential groove arranged in the inner cylindrical portion and a second circumferential groove arranged in the outer cylindrical portion connected by at least one pipe, such that the end piece makes it possible to reduce the weight of the roll by approximately 20%, to facilitate the balancing of the roll while ensuring accessibility to the inside of the roll between the two tubes and to enable easy mounting without indexing due to the circumferential grooves, and where the end piece with spokes enables access to the inside of the roll when it is mounted and thus enables both more accurate balancing than with solid end pieces that require the piercing of the outer tube and the invisibility of this balancing from the outside of the roll.

  • Publication number: 20200016853
    Abstract: A profiled member having two faces and having at least one tear strip with two edges arranged on and adhered to one face of said profiled member, the tear strip having at least one non-adhered edge. The non-adhered edge makes it possible not only to more easily take hold of and remove the tear strip, but also prevents a piece of the tear strip from remaining on the profile member and hindering the adhering of the profiled members to each other. The two edges of the tear strip may be non-adhered, and, when the profile member is covered by a tear strip on each face, the two tear strips are each non-adhered on at least one side. The profile member can be either flat or circular.

  • Patent number: 9227375
    Abstract: A process for producing a bonded connection between first and a second parts, with a length of superposition around a longitudinal axis, these parts being subjected to forces in at least one longitudinal direction, includes producing a bonded connection having at least one interior and/or exterior adhesive joint, over the length between the parts, the joint having a cross-section around the longitudinal axis, the thickness of the joint varying from a free edge on the end-fitting side, to the other free edge on the tube side, and following the direction of forces to which the parts are subjected so as to better distribute the overstresses over at least one part of the length. At least one adhesive joint is produced, having in the longitudinal direction a large thickness facing each of two free edges relative to the thickness in a median part.
