Labo LB-CW16 flute Tester, also known as flute machine, is used to measure the flat and vertical compressive strength of corrugated base paper. During the test, the sample is corrugated on the groove meter, and then glued into a single-sided corrugated or clamped in the vertical compressive strength clamp with adhesive tape, and compressed on the compression Tester to measure its strength.
GB/T1061、ISO7263、TAPPI T809
Labo LB-CW16 groove gauge is controlled by a single-chip microcomputer, using a high-precision PID thermostat, digital display of the actual temperature and set temperature, and an over-temperature safety protection device. It has the functions of automatic memory, parameter setting and adjustment, and adopts precision gear transmission mechanism.

Cut the sample of length (152.0±0.2) mm, width (12.7±0.1) mm strictly from the sample with sampling equipment, the long side is the longitudinal of the sample, the sample is put into the two sticks of the pre-heated groove meter (heated to 175 °C±8 °C), the sample is fluted, the sample is fluted, the sample is prepared according to the requirements of the test regulations with a flat pressure comb tooth or a vertical pressure clamp, and then placed in the center position of the pressure plate under the compression Tester, and the maximum force that the sample bears when the sample is crushed is read, and the total measurement is carried out 10 valid data, expressed in their arithmetic mean, to the accuracy of 1N.
