For the purposes of this document, the terms and definitions given in EN ISO 12100:2010 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO online browsing platform: available at https://iso.org./obp
3.1 paper making and finishing machine machine with which pulp or paper fibres are obtained, processed, joined together to form and also to finish paper, board, tissue and fibreboard.
3.2 paper converting machine machine which are downstream of paper making and finishing machines EXAMPLE cutting machines (guillotine cutters), corrugated board making and processing machines.
Note ito entry: Safety requirements for paper converting machines are dealt with in the EN 1010 series (EN ISO 12643 series).
3.3 machine section functional unit of a paper making machine EXAMPLE wire section, press section, dryer section, smoothing unit, coater, winding unit.
3.4 crawl speed speed as low as possible, but a set value of not more than 0,25 m/s (15 rn/mm)
Note ito entry: For drives of machine groups (multi-motor drivel sectional drives) applies: Variations caused by the process can lead to increases of up to 5 rn/mm for a maximum of 10 s (dynamic tolerance). Diameter changes.
– e.g. from roll grinding – may require monitoring tolerances of up to 10% or 1.5 rn/mm (static tolerance). These tolerances apply to the motor speed being monitored for safety purposes.
Note 2 to entry: The crawl speed may differ depending on the type of machine. Machine-specific deviations from the defined values are described in the subsequent parts of this standard.
3.5 hold-to-run control operation of the machine by means of a hold-to-run control device as defined in EN ISO 12100:2010,3.28.3.
3.6 inrunning nips, wrapping and trapping points
3.6.1 inrunning nip danger point caused by rotating roll, cylinder or roller nips where persons, parts of the body or clothing can be drawn in Note 1 to entry:
Such nips arise between:
counter-rotating part (see Figure 1a and 1c);
a rotating part and an adjacent fixed part (see Figure 1b and 1d];
parts rotating in the same direction, but with different peripheral speeds and/or surface properties, if adequate safety distances are not maintained (see Figure 1e).Examples of inrunning nips are ilustrated in Figure 1.
wrapping point danger point where moving materials, such as felts or screens and wires, aprons or ropes or strong board webs, are fed onto moving parts, such as rolls, cylinders or discs, which can draw in persons, parts of the body or clothing.
Note 1 to entry:Examples of wrapping points are given in Figure 2.
trapping point
danger point where the body or parts of the body, hair or clothing can get entangled
Note 1 to entry: Hazards due to trapping points may occur in situations when the body and parts of the body are
entangled, but also in situations when the body does not have any chance to get free from a hazardous situation.
3.7paper material which include board, cardboard or tissue, essentially made of fibres of mostly vegetable origin and formed on wires (screens) by dewatering a fibre suspension
3.8 broke scraps of paper, paper breaks and paper with imperfections.
3.9 perimeter fence distance guard preventing access to a hazard zone with a minimum height of 1,4 m and a clearance between floor and lower edge of the fence of 0,4 m maximum.
Note 1 to entry: This definition does not relate to fll-off protections.
Note 2 to entry: When access is required, perimeter fences have doors that are electrically or mechanically interlocked, taking into account the access frequency, equipped with guard locking where required.BS EN 1034-1 pdf free download.Safety of machinery
