Abstract:
A unitary cover for a rotary anvil, which anvil presents a cylindrical outer periphery having at least one circumferential slot therein, with the cover being an elongate resilient component and having first and second longitudinal ends and two lateral edges, being adapted to be flexed sufficiently to be mountable upon the anvil periphery for closure thereupon, during anvil usage, further comprising:(a) the cover having an inner and outer surface, both being arcuate while unflexed and having at least one longitudinally aligned, outwardly projecting, linear rail integral within the cover inner surface, the rail being sized and configured to engage upon mounting with the one annular, circumferential slot provided in the anvil outer periphery;(b) the first longitudinal end of the cover being provided with an interlockable, first array of protrusions further comprising:(i) a forked-tongue configuration, first protrusion located proximal to one cover lateral edge, and a single tongue configuration, second protrusion located proximal to the other lateral edge of the cover with both being spaced apart along the first longitudinal end;(ii) a first arcuate-shaped recess contiguous with the first protrusion and overlapping the one cover lateral edge and a second arcuate recess contiguous with the second protrusion and overlapping the other lateral cover edge;(iii) a third recess having a reverse orientation of the forked configuration, first protrusion, which is disposed in-between and contiguous with the first and second protrusions; and,(c) the opposing second longitudinal end of the cover being provided with a complemental second array of protrusions located along the second longitudinal end comprising first and second protrusions, a first arcuate-shaped recess proximal to one lateral edge and an intermediately positioned, forked second recess, proximal the other lateral edge with the recesses being aligned conversely along the opposing second longitudinal end, so as to permit complemental engagement of the second array with the first array disposed transversely along the first longitudinal end of the cover.
