1 Scope
1.1 This European Standard applies to clipping machines
This European Standard specifies safety and hygiene requirements to minimise the hazards which can arise
during the commissioning, the use and the maintenance of clipping machines for portioning and closing of
casings filled with foodstuffs, and intended to be used in butcheries, meat processing factories, main kitchens
and other food processing factories.
This European Standard deals with all significant hazards, hazardous situations and events relevant to
clipping machines, when they are used as intended and under the conditions foreseen by the manufacturer
(see Clause 4).
This European Standard is not applicable to clipping machines which are manufactured before the date of
publication of this European Standard by CEN.
1.2 This European Standard covers the following types of machines:
Concerning the sort of actuation:
 machine for gathering up by hand, power motioned locking-stroke;
 machine for automatic-motioned gathering and automatic-motioned locking-stroke.
Concerning the removal-system:
 machine with removal by fixed or movable clip-guide (see Figures 1 and 2);
 machine with spread-removal (see Figures 3 and 4).

1.3 Description
Clipping machines will be used for closing of tubes with a single-clip (one side) or a double-clip (endlocking
and startlocking).
The machines are equipped with closing tools (punch/die), which make the locking by deforming the locking-
element (clip).
A removal/gathering is used to form a free space and to gather the tube in a way that the locking equipment
can be put over the pressed tail and this can be locked.
By automatic action the clipping machine will be placed at the end of the filling-tube and after each ejecting of
the filling-portion there are positioned one or two clips at the casing.
From the machine the filled portion will be divided with a knife from the skin which still remains on the filling-
tube. If necessary, an additional loop for hanging up the package will be attached.

1.4 Intended use
A clipping machine is designed and constructed in such a way, that in combination with a filling equipment, the
food stuff will be transported through a filling-tube in a casing, which is gathered on the filling-tube. Afterwards
this casing will be closed with a clip.
Furthermore, it is usual to close already filled casings, bags or other packages by hand with a free-standing or
hand-operated/hand held clipping machine.
Although it should be advised against, the standard, taking into account practice, deals with the hazards due
to cleaning with pressurised water.
With the aim of clarifying the intentions of the standard and avoiding doubts when reading it, the following
assumptions were made when producing it:
 only designated and instructed persons operate the machine;
 place of use is adequately lit.

5 Safety and hygiene requirements and/or protective measures
5.1 General
Clipping machines shall comply with the safety requirements and/or protective measures of this Clause and
Annex C of this document.
In addition, they shall be designed according to the principles of EN ISO 12100 for hazards relevant but not
significant, which are not dealt with by this document (e.g. sharp edges).
NOTE For hazards which are to be reduced by the application of a B-standard such as EN 953, EN 1672-2, and
EN 60204-1, the manufacturer should carry out a risk assessment to establish the requirements of that standard which are
to be applied. This specific risk assessment is part of the general risk assessment of the saw.
Where the means of reducing the risk is by the physical arrangement or positioning of the installed circular
saw the manufacturer shall include in the information for use a reference to the reduction means to be
provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification.
Where the means of reducing the risk is by a safe system of working the machinery, the manufacturer shall
include in the information for use details of the system and of the elements of training required by the
operating personnel.
5.2 Mechanical hazards
5.2.1 General
The machines shall be designed in accordance with Annex C and to the conditions mentioned below.
5.2.2 Table-top machines

 guard according to EN 953. This guard can be fixed or movable. If it is movable, it shall be interlocked (or
in accordance with 5.3.7);
 electrosensitive guard according to EN 61496-1. By using light barrier, it shall be in accordance with EN
61496-1:2004, ESPD type 2.
The manufacturer can consider other solutions, but the equivalence shall be established by a risk assessment.
If the top of the machine will be swivelled by hand, there is no technical protection measure necessary.
 Zone 1: closing zone
The access to the danger-points at removal, die, punch and dividing knife shall be restricted (see Figures 12a
and 12b).
• Access from the infeed side
The access to the danger-points through the casing brake of the machine shall be restricted. The inner
diameter D shall be ≤ 60 mm, while the distance A to the danger point shall be ≥ 75 mm (see Figure 14).
• Access from the outfeed side
Access shall be restricted by guarding. The safety distance depending from the opening height shall be in
accordance with the values of Table 1 (see Figures 13 and 14).
NOTE Because of technical construction constrains, the se safety distances are not completely in line with EN 294.
Movable guards shall be interlocked (see 5.3.7).
Safety devices without contact (e.g. light barrier) can be used, if the same safety level is achieved.
