ABSTRACT:
A method for checking operation of a pneumatic splicer for joining two yarn ends at a textile machine includes feeding splicing gas for a predetermined period of time to a splicer to be checked for splicing a particular yarn batch without having yarn ends laid in place in a splicing conduit of a splicer head of the splicer to be checked. At least one status variable of outflowing splicing gas is measured during the predetermined period of time at a given opening in the splicer head. A reference value is measured at another splicer producing replicable spliced joints meeting a previously defined quality and being identical to the splicer being checked, by feeding splicing gas to the other splicer without yarn ends being laid in place in the splicing conduit and measuring the reference value at a given opening in the splicer head. The at least one status variable is compared with the measured reference value and deviations are ascertained. The magnitude of the deviations is used as a basic criterion for evaluating the operation of the splicer to be checked, and satisfactory operation of the checked splicer is then resumed. An apparatus for checking the operation of the pneumatic splicer includes a test apparatus having a splicing gas carrier in the form of a measuring tube. The measuring tube carries an adaptor for connecting the measuring tube to one of the splicer heads and includes a device for detecting at least one status variable of the splicing gas.
