DEVICE FOR MAKING AUTOMATIC MASS HIGH SPEED TENSILE TESTING THREADS

摘要

The invention is related to a composite material testing equipment designed for the automatic, super-speed, and large-scale yarn-strength testing in a manner affording the possibility of displaying and recording the results of the said tests continuously and - practically - at the same time as the test takes place. N pieces of breaking units each of them comprising at least one sensor are mounted upon a common supporting block, and coupled to a single, common drive. The program-controlled drive and the sensors are connected to the control unit of a data processing and control network. The network comprises a RAM-memory connected to several channels of the control unit whereas its data outputs are parallelly connected to the inputs of two registers, the outputs of the registers being coupled to an adder stage, and the output of the latter is connected to a D/A converter. The outputs of the second register are also connected to the data inputs of the RAM-memory, the output of the D/A converter is connected to one input of a set of comparators, the other inputs of the comparators are connected to one of the said sensors each, and the outputs of the comparators are connected to the inputs of channel selector which is coupled with the control unit, and the output of the channel selector is also connected to the respective input of the second register.
