The Industry Standard in Laboratory Handsheet Forming
Proper
laboratory sheet forming capabilities are essential to
manufacturers of paper and nonwoven products, and their
suppliers. M/K Systems has been making automated handsheet
formers for over 20 years, and our instrument is the most
advanced of its kind on the market today. The M/K Series
9000 Automated Sheet Former is particularly well suited for
research in furnish behavior, handsheet quality, effects of
process changes, and chemical effects. Our Sheet Former has
exceptional accuracy in stock and chemical addition, which
enables the refinement of furnishes and chemical use.
Virtually any aspect of a stock or chemical's behavior can
be modeled. The Sheet Former lets you make handsheets with a
precision that no manual process can match. The Sheet Former
is not limited to paper: it can form sheets from any
material that can be laid down in sheet fashion. Fully
automated control ensures the necessary discrimination and
repeatability in handsheet production. Among the options for
the Sheet Former are:
- Number of stocks and
chemicals: Up to six different types of pulp and
eight different chemicals can be mixed for any handsheet.
Individual chemicals can be added incrementally to
successive sheets, providing the ideal mechanism for
guaging a chemical's effects on the sheet.
- Oriented sheets: A
special deckle makes oriented sheets, providing a
handsheet with MD and CD characteristics. The degree of
orientation is controlled by the drainage rate from the
deckle.
- Thick stock tank:
This allows you to mix chemicals with thick stock pulp
(up to 1.5%), especially valuable for chemical
testing.
- Continuous and multi-ply
Sheets: The Sheet Former makes continuous sheets by
overlapping the edges of successive sheets. It also makes
multi-ply sheets by layering sheets on top of one
another.
- Automatic pH and
conductivity control: pH and conductivity can be
monitored and controlled.
- Repeatability: The
Sheet Former operates with 2% repeatability for the basic
weight of successive sheets.
- Customization: All
Sheet Formers are custom-built to individual customer
specifications.
- The Sheet Former makes 12" x
12" (30 x 30cm) sheets
- Range of Materials:
The Sheet Former can make sheets out of virtually any
material that can be laid down into a web. Wood pulp,
fiberglass, numerous synthetic fibers, cotton, kenaf, and
carbon-nickel-stainless steel fibers have all been formed
into sheets.
- The Sheet Former is
controlled by a Windows program, enabling
accurate reproducibility.
The Series 9000 Sheet Former is
especially valuable as a research tool because of the
discrimination that it provides in adding stocks and
chemicals. Over time you can develop correlations between
laboratory handsheeets and the actual production process,
allowing users to predict the effects changes in those
processes while avoiding costly and avoidable downtime. The
SF is the core of any research and development program for
manufacturers of sheet-like or web-based
products.
