Fabric Conveyor Belt Conveyor Belt (Splicing)
Determination of net length
1 Scope
This standard specifies the method of determining the net length of the endless conveyor belt (splice).
This standard applies to all conveyor belts other than steel wire reinforcement.
This standard does not apply to light conveyor belts specified in ISO 21183-1 [3].
2 device
2.1 steel tape measurement, marked with a millimeter scale.
In order to ensure the accuracy of the measurement, the tape should be calibrated or measured.
3 procedures
Expand the endless conveyor belt so that it is flat and free from tension.
As shown in Fig. 1, only a flat portion of the belt is used to draw a point (i.e., point A) on one side of the inner wall as a measurement starting point.
Follow the steps below to mark the point B along the flat portion of the tape.
a) For bands with a circumference of not more than 30 m, except that the length of the last measurement may be less than 1/4 of the circumference,
Should be between the quarter 1/3 and 1/3.
b) For bands with a circumference greater than 30 m, except that the length of the last measurement may be less than 7.5 m, each measurement shall be at 7.5 m
And between the circumference of 1/3.
Measure and record the distance between two points A and B AB.
The rolling belt is continuously measured only along the inner wall of the flat portion of the belt. Each measurement result is denoted as AB, BC, CD, etc., and finally
Always measured XA.
In the event of a dispute, when the supplier and the customer reach an agreement, the measurement should be in accordance with ISO 18573 [2] in a standard environment
get on.
