Abstract: The cutter strip of a dry shaver assembly is formed into a helical configuration by edgewise passage thereof between three rollers which are mounted for rotation about parallel axes and which comprise a main roller and a pair of auxiliary rollers, with the auxiliary rollers having a smaller diameter than the main roller. The cutter strip which is passed between the circumferences of the rollers is formed with undulations extending lengthwise of the strip and the two auxiliary rollers have circumferential slots formed with a width sufficiently large to accommodate the undulations of the strip. The circumferential slots in the auxiliary rollers are offset axially of the rollers to a degree commensurate with the helical pattern which is to be formed.

Abstract: A cover, removably mounted in a recess at one end of a cigarette lighter body, permits access to lighter service points within the recess. The cover includes an integral member formed of a plastics material and having a plate-like body consisting of a first section hinged to a second section by a reduced thickness section of the body. Projections extend from the first section of the body for releasably holding it within the recess. A hollow cylindrical spigot extends from the second section and is secured into the recess by a bayonet-like connection. By lifting the first section out of the recess it can be displaced angularly about its hinged connection to the second section and access can be obtained to the part of the recess covered by the first section. If necessary, the second section can be removed by twisting the plate-like body to open the bayonet-like connection with the lighter body.
