English term or phrase: nips
Het woord nips wordt hier tweemaal gebruikt, maar het is me niet duidelijk wat bedoeld wordt: "All in running nips between rotating rolls and non−rotating parts as well on press nips". Alle hulp wordt geapprecieerd.

nippen
Explanation:
nippen zijn punten waar bijvoorbeeld vingers of kledingstukken verstrikt kunnen raken / geplet klunnen worden tussen twee rollen of tussen een rol en een vast onderdeel.

Example sentence(s):
  • Rotating rolls of the reel create nips. Be extremely cautious when removing waste paper!
  • Draaiende rollen van de opwikkelaar vormen nippen. Wees zeer voorzichtig bij het verwijderen van papierafval!

neutral  Barend van Zadelhoff: Ik heb eerlijk gezegd mijn twijfels over 'nippen'. 'press nips' zou ik vertalen met bv. 'walsspleten in de perspartij', maar de Engelse zin vind ik onduidelijk geformuleerd.

nip
walsspleet; spleet tussen rollen ; grijpzone tussen 2 rollen


Explanation:
NIP
The ‘nip’ of two rolls in a calender or press is the point of contact between the two rollers or rolls.

FABRIC PRESS
Paper machine wet press that uses a special multiple weave fabric belt sandwiched between the regular felt and the rubber covered roll, increasing the capacity to receive and remove water from the nip between the rolls.

GLAZING
First calendering, in which paper is passed through a roll nip to give it a smoother surface.

IATE

nip = spleet tussen rollen ; walsspleet

nip = grijpzone tussen 2 rollen

roll nip adjustment = instellen van de walsspleet

roll-nip = walsspleet

nip-pressure = walsdruk

Why nip?
van Dale: to nip = knijpen / klemmen / beknellen
van Dale: to pinch = knijpen / klemmen / knellen

B) NIPS

These are a specific type of pinch point created by reciprocating or rotating parts. Nips are common at paper machines usually associated with adjacent rotating rolls, where a rotating roll and a moving rope or web come together, or around moving ropes and rope sheaves. These can be hazardous especially to fingers and hands because they are often present in areas where people feed materials into the paper-making process, must add lubricants, or make adjustments.

Nips can be further broken down into two different types:

Ingoing
Outgoing
An ingoing nip is located where two machine parts first meet, and one or both parts rotate. An ingoing nip can easily pull fingers, jewelry, hair, hands and even entire bodies into machinery and equipment. This can lead to serious injuries, including amputations, abrasions, burns, crushing injuries and even death.

An outgoing nip is quite the opposite of an ongoing nip. In this paper machine hazard, not a finger or similar body part will get caught up and crushed, but something that enters the nip point, say for e.g. a hand tool, will pass through the rotating parts and shoot out the outgoing side. It may perhaps strike a person or object after being ejected.

The main safety tip for avoiding projectile hazards from outgoing nips is to keep loose objects away from the nip, that could potentially enter the nip area. Another vital safety tip is to place appropriate machine guarding around the nip when possible.

Wiki / paper machine

nips:

Calender section, where the dried paper is smoothened under high loading and pressure. Only one nip (where the sheet is pressed between two rolls) is necessary in order to hold the sheet, which shrinks through the drying section and is held in tension between the press section (or breaker stack if used) and the calender. Extra nips give more smoothing, but at some expense to paper strength.

There are four main sections on this paper machine. The forming section makes the pulp into the basis of for sheets along the wire. The press section, which removes much of the remaining water via a system of nips formed by rolls pressing against each other aided by press felts that support the sheet and absorb the pressed water.

Here is a diagram of a paper machine (the 'wire mesh' is the 'zeefpartij')

Please compare with 'press section' above

Perspartij
In de perspartij wordt het papier tussen meerdere paren van walsen doorgevoerd. Meestal zijn de walsen bekleed met een persvilt, dat het uitgeperste water opneemt. Dit persvilt is eindloos, dus het opgenomen water moet eruit verwijderd worden voordat dit gedeelte van het persvilt weer in de spleet tussen de walsen terechtkomt. Dit gebeurt met zuigbakken. Er zijn ook perswalsen met gaten, waardoor het uitgeperste water met onderdruk weggezogen wordt.
