Assembly device for binding bunched cables

An assembly device for firmly binding bunched cables with a plastic fastener, said fastener comprising a tension band of indeterminate length having transverse ribs along its length and adapted to be wrapped around said cables and a separate locking clasp having an opening for leading there through the tension band, said opening having two mutually opposite catching tongues that interact with the transverse ribs of the tension band to lock it in place, the assembly device comprising a housing for holding a wound roll of said tension band, an exit opening in one end of said housing through which said tension band can be fed, a first guide channel in said housing having an entrance end and an exit end and positioned for feeding the tension band from said roll to said exit opening, a second guide channel located in said housing above said first guide channel for feeding an endless chain of said locking clasps interconnected together by frangible webs to position the locking clasps one at a time in said exit opening so that the tension band can be passed out through the opening in the clasp, a cutting blade mounted in the housing between a locking clasp positioned in said exit opening and the exit end of said first guide channel, said first guide channel being pivotally mounted in said housing so that the exit end of said first guide channel can be pressed down from the feeding position to bring said tension band down into engagement with said blade to sever said tension band after the band has been firmly wrapped around a bunch of cables and engaged with said locking clasp and spring means for returning said first guide channel to the feeding position.
