BS EN 13954:2005+A1:2010EN 13954:2005+A1:2010 (E) 4 Introduction There are various types of bread slicing machines. They are divided mainly into the following types: Type 1: Frame
23、cutter machines with multiple blades moving vertically; Type 2: Machines with rotary crescent (sickle) or circular blade fixed to a shaft with oscillating movement and horizontal manual loading; Type 3: Machines with crescent blade fixed to a shaft, with a rotating movement and vertical manual loadi
24、ng; Type 4: Machines with one or more rotating band blades. This European Standard is a type C standard as stated in !EN ISO 12100“. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisi
25、ons of this type C standard are different from those that are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

26、13954:2005+A1:2010EN 13954:2005+A1:2010 (E) 5 1 Scope 1.1 This European Standard specifies safety and hygiene requirements for the design and manufacture of bread slicing machines of type 1 and 2 as defined in Clause 3. The intended use of these machines is to cut baked bread into slices. This Europ
27、ean Standard deals with all significant hazards, hazardous situations and events relevant to bread slicers machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard covers requirements for the s
28、afe operation of the machine including: loading, cutting, unloading, cleaning, crumb removal and maintenance. These machines can be manually or automatically operated. 1.2 The following machines are excluded from the scope of this document: experimental and testing machines under development by the
29、manufacturer; frame cutter machines with multiple blades moving horizontally; domestic appliances and machines intended for use by the general public; machines with horizontal circular cutting systems; rectangular cutting machines for cutting or sawing of panel size products into small pieces. The s
30、ignificant hazards covered by this document are described in Clause 4. 1.3 In drafting this European Standard, it has been assumed that the bread slicers falling within the scope are operated only by trained personnel and that the machines are not intended to be cleaned with water jet. 1.4 This Euro
31、pean Standard is not applicable to bread slicing machines which are manufactured before the date of publication of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

The machine is equipped with a lever which acts at the same time as a start/stop control de
46、vice. Type 1b “automatic machines“ (Figure 1.2): the bread is pushed by a power operated mechanical pusher. A control device allows to activate the blades and the pusher until the bread is totally cut and the pusher has come back to the feeding position. Then the machine stops and the cycle is finis
47、hed. The next loaf of bread is placed manually in front of the pusher. Type 1c “automatic machines with continuous feeding“ (Figure 1.3): the machine is fed manually or continuously and the loaves of bread are brought to the blades by (a) conveyor belt(s). 3.2.2 Type 2 machines A type 2 bread slicin
