s especially useful just for shirring, compressing, and packaging, adaptable pipes, including cellulose pipes,that happen to be now typically used as synthetic sausage-casings.
The main thing of your invention is always to provide for the quick shirring and packaging of flexible pipes such form the tubes may beshipped and handled, and put on the horn of any sausage-smiling machine inside the most expeditious and economical way.
Smooth unnatural sausage-casings in the character described are getting made with a large by a famous approach. If possible, this is certainly completed by extruding an appropriate viscose option through an annular orifice in to a coagulating and regenerating bath tub. The regeneration (transformation to cellulose or cellulose hydrate) may be completed in the extrusionbath, or even the hose might be pulled by way of a being successful regenerating bathroom, or bathing, thence via a cleansing bathroom, and ultimately by way of a ,bath tub containing a little percentage of glycerine, or any other hygroscopic representative. This is certainly followed by a drying procedure, and normally the dried out tube is wound in fiat situation on a reel. According to this process, a minute percentage of glycerine remains in the walls of the tube and at tracts enough moisture so that the tube is suffi- .ciently soft and pliable, although dry to the feel.
By the method referred to, a seamless cellulose tube which is several hundred feet in length may be loaded onto a single reel. It can be desired to slice this into perfect length to use in packing properties, and package deal these lengths in ideal develop fortransportation and handling, and employ from the packing residences. This objective is completed from the present technology.
The technology is illustrated in the recommended embodiment in the associated sketches, which illustrate the approach utilized and the favored embodiment of the machine effectively adjusted to practicing these kinds of approach.
It may be preliminarily, that and stated in line with the recommended practice, a continuous hose is fed from the appropriate supply of supplyonto a hovering mandrel which happens to be releasably supported at a number of factors (ideally at two things by releasable clamping-units); a gaseous method is launched through the mandrel to inflate the part of the hose that is presently to become shirred; the shirring procedure is performed around the higher area of the tube through orbitally transferring shirrers which indent the infiated tubing at spaced points and have the tube forwards againstan abutment (one of several releasable clamps of your mandrel) the shirred-length of the tube is then transferred forward by the owner (right after releasing the clamp just pointed out) into the making it portion of the mandrel as well as the hose-is severed in the back from the shirred segment; a fresh shirring functioning irmnediately begins on a fresh entire tube; the innovative shirred-duration, although continue to on “the mandrel, is put through longitudinal pressure against an abutment (the clamp in the intense improve stop of the mandrel) and the very last-described clamp is launched from the proprietor plus a cardboard pot is applied towards the shirred, compressed pipe-duration although it still remains around the mandrel, then the packaged tube is taken away from your progress end in the mandrel.
