ABSTRACT

Bobbins containing convoluted webs of sheet material, particularly wrapping
material for smokers' products, are transferred from a stack—wherein the
axes of the cores of bobbins are vertical—onto the horizontal stub of a
receiver in a web processing machine by an apparatus wherein a first set of
jaws serves to engage the core of a fresh bobbin from within preparatory to
transfer to the receiver and simultaneous pivoting of the first set of jaws
through 90°. When the supply of web on the core borne by the stub of the
receiver is exhausted, the external surface of the thus exposed core is
engaged by a second set of jaws which transport the core to a collecting
station or the like. Sheet-like partitions which are disposed between
neighboring layers of fresh bobbins in the stack are removed by suction cups
which are mounted on a reciprocable pusher together with the jaws of the
second set.
