Paper Cone Collapsing Strength Tester

Paper Cones are generally used as yarn carriers.

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 paper cone. 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 paper cone.

Collapsing strength tester is designed in such a manner that gradually increasing force is generated & applied on the surface of the paper cones. 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.
