EN 972:1998+A1:2010

This European Standard specifies safety requirements for all the phases of the life of a machine listed in5.3 a) of EN ISO 12100-1:2003.Reciprocating roller machines are machines used for the processing of animal hides and skins. They have a reciprocating opening and closing motion of the feed rollers or conveyors which, if required, may also reverse their direction.This standard covers the following reciprocating roller machines (see figures 1 to 13 for typical configurations and annex D for descriptions):a)Buffing machines (see figures 1a and 1b)b)Polishing machines (see figures 1a and 1b)c)Ironing machines (woolskins and fur) (see figures 2a and 2b)d)Carding machines (see figures 3a and 3b)e)Shearing machines (woolskins and fur) (see figures 4a and 4b)f)Cylinder universal staking machines (see figures 5a and 5b)g)Setting-out machines (see figures 6a and 6b)h)Dewooling machines (see figures 6a and 6b)i)Scudding machines (see figures 6a and 6b)j)Unhairing (dehairing) machines (see figures 6a and 6b)k)Sammying machines (see figures 6a and 6b)l)Cylinder ironing machines (see figures 7a and 7b)m)Cylinder staking machines (see figures 8a and 8b)n)Fleshing machines (see figures 9a and 9b)o)Demanuring machines (see figures 10a and 10b)p)Wet wheeling machines (see figures 11a and 11b)q)Shaving machines (feed-out) (see figures 12a and 12b)r)Shaving machines (feed-in) (see figures 13a and 13b)It takes account of intended use, foreseeable misuse, component and systems failure.This European Standard is not applicable to reciprocating roller machines which are manufactured before the date of its publication as EN.This European Standard provides provisions for the reduction of noise emission at the design stage (see 5.2.4 and Annex A). However, it does not provide a noise test code for the determination by measurement of noise emission values for the machines it covers. Without such a code the manufacturer c
