ISO 11111-2:2005(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11111-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for dry-
cleaning and industrial laundering, Subcommittee SC 8, Safety requirements for textile machinery.
This first edition of ISO 11111-2, together with ISO 11111-1, ISO 11111-3, ISO 11111-4, ISO 11111-5,
ISO 11111-6 and ISO 11111-7, cancels and replaces ISO 11111:1995, which has been technically revised.
ISO 11111 consists of the following parts, under the general title Textile machinery — Safety requirements:
 Part 1: Common requirements
 Part 2: Spinning preparatory and spinning machines
 Part 3: Nonwoven machinery
 Part 4: Yarn processing, cordage and rope manufacturing machinery
 Part 5: Preparatory machinery to weaving and knitting

ISO 11111-2:2005(E)
Introduction
ISO 11111-1 to ISO 11111-7 were prepared simultaneously by ISO/TC 72 and CEN/TC 214 and adopted
under the Vienna Agreement in order to obtain identical standards on technical safety requirements for the
design and construction of textile machinery.
ISO 11111 as a whole is intended for use by any person concerned with the safety of textile machinery, for
example, textile machinery designers, manufacturers and systems integrators. It is also of interest to users of
textile machines and safety experts.
This document is a type C standard as stated in ISO 12100-1. The various parts of ISO 11111 deal with
significant hazards generated by machines used in the textile industry. The machinery concerned and the
extent to which hazards are covered are indicated in the scope of this standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence.
For hazards of machines or machine elements not dealt with in the relevant part of ISO 11111, the designer is
to perform a risk assessment according to ISO 14121 and evolve means for reducing the risk from significant
hazards.
This part of ISO 11111 is intended to be used in conjunction with ISO 11111-1. As far as possible, the
requirements of this part of ISO 11111 are treated by way of reference to Clauses 5 and 6 of ISO 11111-1.
Clause 5 of ISO 11111-1 contains safety requirements and/or measures for frequently occurring hazards of
textile machinery which apply whenever referred to in this part of ISO 11111, while Clause 6 describes
significant hazards and corresponding safety requirements and/or measures for certain machine elements and
their combinations (e.g. rollers), which also apply whenever referred to in this part of ISO 11111.

Specific hazards
Mechanical, from drive and transmission parts for particularly dangerous machine elements, when the longest
stopping time exceeds the access time (e.g. crushing, shearing, entanglement, drawing-in and trapping).
Specific risks
Occasional access during special operations, particularly during changing of transmission parts, removal of
fibre material, cleaning, stripping, grinding, leading to high probability of severe injury. There is a particular risk
during run-down of rotating machine elements and associated drives.
Specific safety requirements
Interlocked movable guards with guard-locking in accordance with ISO 11111-1:2005, 5.3.3 shall be provided
for drive and transmission parts such that they cannot be opened or removed if required for technical reasons
until the drives and transmission parts have been brought to a standstill. For example, a guard-locking device
in conjunction with a motion sensor or a timer can be used for this purpose. The guard-locking device shall

---------------------- Page: 13 ----------------------

ISO 11111-2:2005(E)
keep the guard closed when the control system or power supply fails. The precautions for drive and
transmission parts may be designed also to protect particularly dangerous machine elements simultaneously
[see ISO 11111-1:2005, 6.3 a)].
5.2.2 Automated blending bale openers
These include machines with a tower, running on a fixed track, parallel to which one or two lines of bales are
laid. A horizontal arm projects from the tower at right angles and has a milling head on its underside.
The operating area over which this machine works is relatively large. Ready access is required to the currently
non-operational side, or to the currently non-operational section, to install the next complement of bales in
their working position.
General safety requirements
The safety requirements of 5.2.1 shall apply.
Specific hazards
Mechanical, from the milling head, in particular, entanglement, drawing-in or trapping, impact, and from the
wheels, in particular, crushing.
Specific risks
Occasional access during normal operation, particularly for picking up flock from the floor and during special
operation, particularly cleaning and removal of blockages, leading to a moderate probability of severe injury.
Specific safety requirements
a) Automated blending bale openers shall be provided with guards or safety devices to prevent access to
the operating milling rollers.
b) In deviation from ISO 11111-1:2005, 6.3, this may be achieved by one of the following:
1) A trip device to stop the milling roller immediately when an operator enters the zone within which the
milling roller is operating. For example, a system of active opto-electronic protective devices (AOPD),
in accordance with ISO 11111-1:2005, A.2, may be used around the boundaries of the operating
zone, as in Figure 1, to act as a trip device.
Where the height of the fibre tunnel in the middle of the two operational zones is 300 mm or more,
the lower beam may be omitted in the tunnel area.
As an alternative to AOPD, pressure-sensitive mats and floor according to EN 1760-1 or pressure-
sensitive edges and bars according to EN 1760-2 may be used.
The restart control shall be located so that it cannot be actuated from inside the operation zone.
2) A provision during the normal production mode to protect any section of the milling roller not engaged
with a bale, either by completely encasing the roller or by fitting a trip device or devices that stop the
roller before access can be gained; provision shall be made for the rollers to come to a standstill as
soon as the milling roller traverses beyond the line of bales, or is raised above the bales.
In either case, a category of 3 or 4 according to ISO 13849-1:1999, Clause 6 of the safety related
part of the control system shall be selected.
c) A signal to warn of automatic restart shall be installed (see ISO 11111-1:2005, 5.4.2.3).
d) Suitable support devices shall be provided for the milling roller arm to prevent the arm dropping
unexpectedly. This may be in the form of two ropes, each of sufficient strength to support the arm.

ISO 11111-2:2005(E)
e) A warning shall be given in the instruction handbook concerning the need to install the machine in such a
position that the moving parts (e.g. the arm or the tower) do not pass closer than 500 mm to fixed
structures within the work area (see ISO 13854) or to safeguard the crushing zone .
f) A device shall be provided to bring the tower to a standstill before it reaches the end of the track (see
ISO 11111-1:2005, 6.21.3).
g) Wheels shall be protected according to ISO 11111-1:2005, 6.7.1.
