Paper core compression tester

1. Core Compression
Model # P500/1000D
Core Compression Tester
Paper tubes and bobbins are used as yarn carriers while paper cores are generally used for paper & plastic film
The collapsing force, which the carriers are capable of resisting, is dependent upon the following factors:
- Quality and Quantity of paper
- Quality and Quantity of adhesive
- Manufacturing process
- Moisture content in the carrier
- Physical size and dimensions
It is very difficult for a user to know all the above factors
and their influence on the strength of the carrier. It is
equally difficult for a manufacturer to know the effect of
each variable quantitatively.
But it is very easy for both the user and manufacturer to
differentiate between good and bad and adopt a suitable
standard of monitoring the quality of the carrier.
Collapsing strength tester is designed in such a manner that
gradually increasing force is generated & applied on the
surface of the carriers. The sharp collapsing point can be
easily detected with the help of a Loadcell and
Microprocessor based digital indicator.
Since this machine directly measure the collapsing force, no calculations are required and hence, the readings
are direct and most accurate.
For Paper Tubes / Cores used as Winding Medium / Carrier, Radial Crush Test is performed.
For Paper Tubes / Cores used as Packing Material, Flat Crush Test and Vertical Crush Test can be performed.
