Along with upgrading of paper quality and diversification of paper kinds, the requirements for paper quality are diversified, and especially for printability, this trend is remarkable. Generally, the size press is provided with two rollers to coat size liquid on the surface to increase the surface strength of a wet paper at the press part of the paper making machine, after dewatering press, or to improve printability. The inclined type is more effective and of lower cost than the conventional inner sizing type using beater additive. In addition, the size press is widely used at the process of on-machine coating for application of primer for topcoat, bearing an important role to improve paper quality and printability. This test size press can simulate as many conditions as possible of a practical paper making machine, using an excellent system with ease of handling, and ensuring high reproducibility. The mechanism is designed as follows; this is an inclined type press with two rollers of special material being laid at an inclination of 35 degrees. From the liquid tank, the size liquid is fed through a pipe onto the rollers, forming a dam of liquid between them. Between the rollers in such a state, is inserted the paper sheet semi-dried or dried (sizeless), then immediately the paper sheet is pressed in the roll nip.
As an option, there is a model equipped with a coating-liquid heating and circulating system and with a device to humidify the press roll.

The size solution for surface sizing penetrates and stays in the paper surface while it circulates in the group of rollers of a paper-making machine. During this process, gummy aggregations form in the size liquid, affected by the contact heat of continuous paper and mechanical shear force. After winding and drying, such gummy substance forms defects on the paper surface. There are two types of machines, A and B models. The model A is a tester applying nip pressure on the rollers, with a pump to let the size liquid circulate from the constant temperature tank. With this machine, it is possible to reproduce the conditions of an actual paper making machine for the user to know in advance the stability and mixing of ingredients.

The model B is a simplified type to take out size liquid from the pan through the lower roll and introduce it into the nip between two rollers. By so doing, the desired shear force is produced, and the observer can monitor and evaluate change in state of the liquid. This tester is also used as a simplified roll coater for the coating machine.

The test mangle is widely used for impregnation processing of papers and woven textiles, capable of adjusting the gap between the rollers with the right and left screws. This tester is designed to apply pressure uniformly on the right and left sides, most suitable for operations in the laboratory.
There are two types, manual with handle and motor-driven.
