Latticed grid mfr. - by cold pressing support rods and cross-rods into each other

摘要

A latticed grid is made by cold pressing together support and cross-rods which are free from slits and holes The cross-rods (2) have a smaller width than the support rods (1) and are round, square or rectangular in cross-section. Either the rod of a hard material is pressed into the rod of the softer material, or the two types of rod of similar hardness are each pushed into the other. USE/ADVANTAGE - As covers for stages, dias and steps. Is cheap to produce as the rods do not have to undergo any preworking to cut in slots, holes, etc.
