摘要:
A slitting and scoring machine includes an upper tooling roller and a lower tooling roller that cooperate to define a tooling nip. Each tooling roller includes an alternating series of coaxially arranged annular knives, annular dies, and annular mandrels. A web of insulation is drawn through the tooling nip to simultaneously (i) cut the web into strips, (ii) score the strips in a manner that promotes the forming of the strips, and (iii) partially form the strips into modified U-shapes. Each strip includes a longitudinally extending middle segment and a pair of longitudinally extending side segments that extend away from the middle segment in a divergent manner to define a longitudinally extending channel. Longitudinally extending grooves are formed by the scoring at the junctures of the middle segment and the side segments. The scoring/grooves promote the divergent shape of the strip. In an end profile view of the strip, the middle segment and each of the side segments are generally straight, and an obtuse angle is defined between each side segment and the middle segment. Each strip is formed into a roll, so that a first length of the strip and a second length of the strip each extend around a common point. At least a portion of the second length is disposed within the channel of the first length.

A support and display assembly for a plurality of thin, relatively lightweight objects such as floppy disks or diskettes, wherein a support frame has a plurality of holder structures rotatably mounted therein and annularly pivotal between two oppositely disposed angularly oriented positions wherein each of the holders and any object contained therein is disposed in a spaced apart, parallel relation to one another when in either of the two opposite positions and further wherein a braking structure is provided to restrict the pivotal movement of the holder structure such that such holder structures will not "automatically" successively travel between the aforementioned opposite positions by a forced displacement of one of such holders.
