Cleanroom Paper Roll NB-MF50G

A slotted-core roll for a matched printer interface

NB-MF50G is a light-basis-weight pulp/polyester wiping roll with a slotted plastic-core configuration. The slot is a functional interface, not simply a cosmetic difference from a plain-ended roll. Its engagement with the printer's drive or holder must be checked along with the tube dimensions.

The wiping web is used to collect residue during automated stencil underside cleaning. Its suitability depends on stable feeding and on the cleaning process selected for the paste, stencil and equipment. The product name does not establish that it fits every machine within a printer brand.

What to measure on the existing core

Take measurements from an undamaged core that is known to work in the machine. Record its end-to-end length, bore, outer diameter and any ribs. For the slot, record width, depth, number and position. Include a photograph of each end and identify which end drives the roll. These details avoid interpreting a single nominal diameter as a complete interface specification.

Also identify how the material is wound relative to the tube ends. Equal overall core lengths can carry different web positions, and a correctly sized tube can still place the wiping surface off centre.

Keep supply and use specifications together

The carton quantity is a packing format; it is not a statement of how many boards a roll will clean. Consumption varies with advance length, cleaning frequency and the printing process. Track actual roll changes on the line to establish replenishment needs, then keep the approved core drawing attached to the ordering code.

Separate accepted rolls from samples being evaluated. Store opened rolls so their exposed edges cannot collect debris, and bring only the required quantity to the loading station. The configuration can be customized to the machine interface and handling requirements.

Core profiles and converted roll details

Plain, single-slot, cross-slot and ribbed cores use different mounting arrangements. The photographs show available format types across the roll range. Confirm the selected construction, bore, end dimensions and winding position for the individual order.

Printer-family format guide

These format combinations are provided for checking conversion requirements. A printer brand can use several cleaning assemblies: verify the exact model and installed cassette before selecting a row. Dimensions are core length, core inner diameter, paper width and wound paper length; they do not specify the complete slot geometry or guarantee fit.
