Abstract
Tubing typically produced by an extruder is advanced to coiling apparatus and is cut to predetermined lengths. The automated apparatus includes a plurality of spindles arranged at spaced intervals about a turret, which is indexed to position each spindle to: receive, clamp and coil the last cut length of tubing; advance the coiled length of tubing to a taping station, where the spindle so advanced is rotated for application of tape at diametrically opposed locations, and advance the spindle to an ejection location, where the spindle ejects the taped coil of tubing. The taper advances a pressure-sensitive tape strip, strips a protective strip from the tape and applies the tape to the applicator surfaces of a jaw assembly which swing together causing the tape to envelope the coiled tubing and presses the ends of the pressure-sensitive tape strip together to complete the taping function. The jaws of the jaw assembly are then separated, and the jaw assembly is withdrawn from the coiled tubing. The spindle undergoes a half-revolution rotation in readiness for a second taping application and withdrawal of the jaw assembly permitting advancement of the taped coil to the ejecting station, …
