This document specifies safety and hygiene requirements of clipping machines (hereafter referred to as machine) for closing of casings filled with foodstuffs (hereafter referred to as product) by using a clip, and which are intended to be used in butcheries, meat processing factories, main kitchens and other food processing factories. Clipping machines are used to close tubes with a single clip (one side) or a double clip (end locking and start locking). The machines are equipped with closing tools (punch/die), which create the closure by deforming the locking element (clip). This document deals with all significant hazards, hazardous situations and hazardous events relevant to machinery when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document covers the following types of machines: – semi-automatic machine (see Figure 1 and Figure 2); – automatic machine (see Figure 3). This document does not cover any machines whose closing procedure is only performed manually. This document is not applicable to machinery manufactured before the date of publication of this document by CEN.
