Abstract
A tube squeezing device includes a pair of hollow external rollers and a self-adjusting tension-applying support frame assembly rotatably supporting the external rollers and including a pair of internal stabilizer tubes which extend through the external rollers and a pair of self-adjusting end retainers having a pair of opposite end flanges adapted to abut against the opposite ends of the internal stabilizer tubes, a pair of elongated connector guide pins rigidly attached to opposite end flanges and extending axially therefrom to form tightly fitted connections within the opposite hollow ends of the internal stabilizer tubes, and a middle arcuate-shaped self-adjusting tensioner member extending between and rigidly connected at opposite ends to the opposite end flanges. Also, either the opposite ends of the stabilizer tubes or opposite end flanges of each end retainer have annular hubs formed thereon which fit within the respective opposite ends of the external rollers and provide bearing surfaces about and upon which the opposite ends of the external rollers ride and are rotatable relative to the support assembly. The arcuate-shaped tensioner members of the end retainers are suffic…
