Abstract

Abstract A novel fastening device for securing a blanket or cover on a cylinder includes a split ring annular band terminating at one end with a mounting member of U-shaped cross section and a fastening element at the opposite end formed from an elastically deformable material. The fastening element is held in deformed engagement by the opposite side walls when the cover is mounted on a cylinder.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 168 words
A fastening device for releasably securing a split ring annular member around a rotary die cutting machine cylinder body comprising: a non-elastically deformable mounting member and a fasTening element coextensive in length, said mounting member adapted to fit within a slot provided in a cylinder and being generally of U-shaped cross section, and said mounting member including a longitudinal flange of an elastically deformable material partially restricting the opening of said mounting member and extending partially into said mounting member, said fastening element including a projection for cooperative engagement with said mounting member flange when in a fastened position, said fastening element being of an elastically deformable material, whereby said fastening element will conform to said mounting member sufficiently to be retained thereby when in operative engagement but permit forceable separation of said fastening element and mounting member; means for attaching said fastening element to one end of said split ring member; and means for attaching said mounting member to the opposite end of said split ring member.
Claim 2
Dependent Claim 168 words
A fastening device for releasably securing a split ring annular member around a rotary die cutting machine cylinder body comprising: a non-elastically deformable mounting member and a fasTening element coextensive in length, said mounting member adapted to fit within a slot provided in a cylinder and being generally of U-shaped cross section, and said mounting member including a longitudinal flange of an elastically deformable material partially restricting the opening of said mounting member and extending partially into said mounting member, said fastening element including a projection for cooperative engagement with said mounting member flange when in a fastened position, said fastening element being of an elastically deformable material, whereby said fastening element will conform to said mounting member sufficiently to be retained thereby when in operative engagement but permit forceable separation of said fastening element and mounting member; means for attaching said fastening element to one end of said split ring member; and means for attaching said mounting member to the opposite end of said split ring member.
Claim 3
Dependent Claim 147 words
A rotary die cutting machine cylinder blanket comprising in combination; a split ring annular band member having a first end and a second end; a mounting member of U-shaped cross section attached to the first end of the split ring annular band backing member, said mounting member adapted to fit within a slot in a rotary die cutting machine cylinder; an elastically deformable cover on said backing member, said cover extending, at said first end, partially over the opening of the U-shaped mounting member and forming thereby a longitudinal flange, said elastically deformable cover extending beyond said second end of the backing member and defining a fastening member of the shape and size adapted to be deformably received in said mounting member when said mounting member and fastening element are in operative engagement whereby a continuous cover is provided when the blanket is mounted on the cylinder.
Claim 4
Dependent Claim 147 words
A rotary die cutting machine cylinder blanket comprising in combination; a split ring annular band member having a first end and a second end; a mounting member of U-shaped cross section attached to the first end of the split ring annular band backing member, said mounting member adapted to fit within a slot in a rotary die cutting machine cylinder; an elastically deformable cover on said backing member, said cover extending, at said first end, partially over the opening of the U-shaped mounting member and forming thereby a longitudinal flange, said elastically deformable cover extending beyond said second end of the backing member and defining a fastening member of the shape and size adapted to be deformably received in said mounting member when said mounting member and fastening element are in operative engagement whereby a continuous cover is provided when the blanket is mounted on the cylinder.
Claim 5
Dependent Claim 30 words
The device of claim 2 wherein said cover extending partially over the U-shaped mounting member includes a groove and said cover at said second end includes a matching lug extension.
Claim 6
Dependent Claim 20 words
The device of claim 2 wherein said mounting member is adapted to fit snugly within a slot in a cylinder.
Claim 7
Dependent Claim 34 words
The device of claim 4 wherein said mounting member includes a bolt hole in the base thereof whereby a bolt can be inserted through said hole for bolting said mounting member to the cylinder.
