1.1 This European Standard applies to the design and manufacture of moulders of the types described from 3.2.1 to 3.2.4 and illustrated in Figure 1 to Figure 3.
These moulders are used separately or in a line in the food industry and shops (pastry-making, bakeries, confectionery, etc.) for flattening, rolling and, but not necessarily, elongating pieces of dough. These machines can be fed by hand or mechanically.
This document deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of moulders, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
1.2 This European Standard does not deal with:
-
designs of moulder other than those described from 3.2.1 to 3.2.4;
-
experimental and testing machines under development by the manufacturer;
-
domestics appliances;
-
bagel machines;
-
additional hazards generated when the machine is used in a line;
-
dough and pastry brakes (see EN 1674).
1.3 This document is not applicable to machines which are manufactured before its date of publication as a European standard.
