Abstract

An apparatus for squeezing and re-rounding a plastics tube in two modes of operation. When the plastics tube is squeezed, any flow or fluid therein is stopped. The advantage of the apparatus is that the modes of operation can be performed on the single piece of apparatus and different sizes of pipe can be accommodated by predetermined adjustment of stops on the equipment. <IMAGE>
