Multiroll cradles
Multiroll cradle is designed from three or more small diameter iron cylinders, fixed
side to side of the spreading machine (see Fig. 6.6). Two, one, or no one cylinder is
motor-driven, others freely moving. The cradle normally has one more motor-driven
cylinder (a traction cylinder) fixed on the front of the machine that pulls the fabric
from the cradle. This is the simplest way to manufacture a cradle. However, multiroll
cradles cannot ensure qualitative tension-free spreading. Normally, winding of the
fabric roll can be performed manually, but rewinding is not possible.
Multiroll cradle feeding systems are used on some spreading machine models by

Advantages and disadvantages of the cradle type of feeding systems
Advantages– Cradle-type fabric feeding system can ensure tension-free spreading for
all kind of materials and also for fabrics that are hard to unwind or have a tendency to
stretch or to come off the roll in an uneven manner; the system enables easy loading
