The rope ① will be blown-in directly from the storage drum ② into the duct ③.
A blowing-in piston ④ at the beginning of the rope will be forced through the pipe by compressed air of a compressor ⑤.
The pipe is sealed by a sealing plug ⑥ with rope-slit.
The capstan drive ⑦ of the rope reel ⑧ will be used for pulling the rope back to the starter manhole.
