Abstract
A press-on roller which is usable to press a first paper web into contact with a second paper web includes a support tube and a resilient press-on sleeve which is concentric with the support tube and separated from it by an annular space. This annular space is provided with at least one and preferably with a plurality of gas-filled cells. These gas filled cells provide the press-on roller with a controllable resiliency.
Claims19
A press-on roller for pressing a first moving web of material to the beginning of a second moving web of material wound on a rotating web supply reel comprising:
- a central support tube having spaced first and second ends and a longitudinally extending axis of rotation;
- first and second annular end caps secured to said first and second ends of said central support tube;
- an elastic hollow cylindrical press-on shell, said press-on shell being supported by said first and second end caps and extending coaxially to said support tube and having an active length corresponding to a width of a moving web of material;
- an annular space defined by said central support tube, said press-on shell and said end caps;
- and
- at least one gas-filled cell in said annular space, said at least one gas-filled cell resiliently supporting said press-on shell spaced from said support tube.
A resilient press-on roller for pressing a depleting paper web into engagement with a surface of a new paper web on a fresh paper web supply reel, said press-on roller comprising:
- a central support tube having spaced first and second ends, an outer surface and being rotatable about a longitudinally extending axis of rotation;
- first and second end caps secured to said first and second ends of said central support tube;
- a resilient press-on shell supported by said first and second end caps coaxially with, and spaced from said support tube;
- an annular space defined by said outer surface of said support tube, said first and second end caps and said press-on shell;
- and
- a plurality of gas-filled cells situated in said annular space to resiliently support said press-on shell spaced from said central support tube.
