Abstract

A staple feeder mechanism 3 feeds staple sticks S from a magazine 2 to the head 5 of a stapler along a rail 4 and biases the stick into position for stapling. The mechanism 3 com-prises an endless belt 20 which extends over guide rollers 21, 22 and frictionally engages the crown of a staple stick beneath it, The belt may, for example, be made of a natural or synthetic elastomer such as a soft grade of polyurethane or of a rubberized fabric. The belt may be driven intermittently, being actuated by movement of the staple driver 1 for example, or continuously, as by motor M-

A staple feeder mechanism 3 feeds staple sticks S from a
magazine 2 to the head 5 of a stapler along a rail 4 and biases
the stick into position for stapling. The mechanism 3 com~
prises an endless belt 20 which extends over guide rollers 21,
22 and frictionally engages the crown of a staple stick
beneath it, The belt may, for example, be made of a natural or
synthetic elastomer such as a soft grade of polyurethane or of
a rubberized fabric. The belt may be driven intermittently,
being actuated by movement of the staple driver 1 for example,
or continuously, as by motor M~

To avoid damage to the staple stick, the driving force is
limited either by the belt sliding over the staple stick or by
force limiting means in the belt drive,

IMPROVEMENTS IN STAPLERS (Cont~d)

The staple sticks are arranged side by side in the magazine
and spring urged into alignment with the mechanism 3~ In the
drawing three sticks are visible: a partly consumed stick Si
on the rail 4, a complete stick S2 partly on the rail 4 and
partly in the magazine and the next stick S3 to be fed,

The staple stick may be supported in other ways than shown and
the belt 20 may engage the inside face of th...
