The hardness of paper rolls is an important quality factor in the working processes of the paper, film and foil industry. Rolls that are too hard, or too soft, rolls that are unevenly wound, or rolls with different moisture contents can cause difficulties during the printing process. The hardness control of such rolls, in particular their uniformity over the whole width, has to date created many problems.
Paper Schmidt
By taking Leeb readings across the roll, uneven, too soft or too hard winding can be detected and the roll can be rejected. This minimizes the risk of complications e.g. during the printing process on paper. Salient Features of MF300F+
Paper Schmidt
The Paper Schmidt is the first rebound hammer designed specifically for the testing of the roll profile. The instrument is fully compliant with the TAPPI T834 om-07 standard used in North America to regulate the test of the paper roll profile and it delivers instantly all of the key parameters required for assessing the quality the of paper roll.
In addition to this the Paper Schmidt has an extended lifetime to cope with the heavy demands of the paper industry and dedicated tools, such as pre-defined tolerances that make assessing a roll profile a simple matter.

Equotip 2
The Parotester 2 roll hardness tester provides accurate and reliable evaluations of the roll hardness, hardness profile and hardness variation of paper, foil and film rolls. With Parotester 2 unevenly wound reels can be spotted prior to interruption of operations and cause of quality problems in printing and converting operations.
By taking Leeb readings across the roll, uneven, too soft or too hard winding can be detected and the roll can be rejected. This minimizes the risk of complications e.g. during the printing process on paper. Salient Features of MF300F+
- The Leeb hardness value (HL) immediately indicates the winding tightness. The measurement with the roll hardness tester is objective and precise
- The high resolution (1 LU) facilitates comparatively small differences in hardness to be revealed
- The large LCD display of the roll hardness tester enables an immediate visual assessment of the values
- The unit can be easily programmed for individual user requirements
- About 5000 single measurements can be stored internally. The data can be retrieved via RS 232C for further processing on a PC (use Parolink 3 or HyperTerminal software) or directly printed
- Using the external barcode reader (accessory part), roll identifications can be quickly captured and accurately read from the barcode of rolls
- This roll hardness tester is well suited for the paper industry
- Foils, films and other plastic sheet materials where a low impact energy is required
