<p>OBJECT-TURNING APPARATUS FOR A HIGH-SPEED STRAPPING MACHINE An object B is deposited at a strapping station 12 on a high-speed, rapidly accelerating conveyor 10 having a highfriction conveying surface. The object B is raised off the high-friction surface by spaced tables 40 and 42 having lowfriction surfaces. Spaced, vertically downwardly extending bars 28 and 30 engage opposite halves of opposite sides of the object B and simultaneously move those halves transversely so as to rotate the object B ninety degrees on the low-friction tables. A first strap 51 is placed around the object B before it is rotated; a second strap 52 is placed around the object B after it is rotated ninety degrees; then the conveyor accelerates the cross-strapped object B rapidly out of the strapping station 12.</p> |
