Food processing machinery. Band saw machines. Safety and hygiene requirements. | Status: Revised, Superseded, Withdrawn

1 Scope This European Standard specifies requirements for the design and manufacturing of band saw machines (see Figures 1 to 5). The machines covered by this European Standard are used to cut bone and meat. The band saw machines covered by this European Standard do not include band saw machines for processing wood and similar materials and the requirements of EN 1807 do not apply. Band saw machines for domestic use are not included in this European Standard. This European Standard only applies to machines which are manufactured after the date of issue of this European Standard. This European Standard covers the following types of machines: Band saw machines which are placed on the floor and can be wheel-mounted (see Figure 6).

• — Type A

Band saw machine with a feed table and a fixed product pusher Cutting height SH < 250 mm

• — Band saw machines designed as table-top machines with and without base
• — Band saw machines designed as floor-type machines
• — Band saw machines integrated in a cutting line

Location: Table (see Figure 1) or base (see Figure 2). Distance A from the floor to the top surface of the feed table is between 800 mm and 1050 mm. Figure 1 — Type A, Band saw machine with product pusher - Location: table top 1 ON / OFF switch 2 Product pusher 3 Portioning plate 4 Table Figure 2 — Type A, Band saw machine with product pusher - Location: base 1 ON / OFF switch 2 Product pusher 3 Portioning plate 4 Base

• — Type B

Band saw machine with a feed table, a protective rail and a cutting height 250 mm < SH < 420 mm. Distance A from the floor to the top surface of the feed table is between 800 mm and 1050 mm. Location: floor (see Figure 4)

• — Type C

Band saw machine with a sliding feed table, a protective rail and a cutting height 250 mm < SH < 420 mm. Distance A from the floor to the top surface of the sliding feed table is between 800 mm and 1050 mm. Location: floor (see Figure 4).

• — Type D

Band saw machine with feed and removal unit (e.g. roller conveyor, conveyor belt); integrated in a cutting plant, cutting height SH < 550mm. Distance A from the floor to the feed surface is between 800 mm and 1050 mm. Location: floor (see Figure 5). Figure 5 — Type D, Band saw machine with feed and removal unit 1 Roller conveyor or transport conveyor Band saw machines consist of a machine casing, a fixed feed table or a sliding feed table, a roller conveyor or conveyor belt, a product pusher, a height-adjustable protective rail, a top and a bottom wheel, a saw blade, an upper and lower blade guide, a blade tensioning device, a drive and electrical components, depending on machine type. The requirements for automatic loading/unloading systems, conveyors, etc. do not fall within the scope of this European Standard. This European Standard deals with all significant hazards, hazardous situations and events relevant to band saw 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 deals with the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine. On floor-type band saw machines, the product to be cut is placed by hand onto the fixed feed table or sliding feed table and pushed against the cutting zone of the saw blade by means of the product pusher or the rear table wall on the sliding feed table or by means of the roller conveyor or conveyor belt and sawed.
