has a surface adapted to abut against the saw blade, and also a second side
which is remote from said clamp holder and has a wedge-shaped surface;
a wedge piece having a wedge-shaped surface abutting against said
wedge-shaped surface of said clamping piece and also having an opposite
surface;
a first spring acting on said wedge piece in a direction essentially
perpendicular to a displacement direction of said clamping piece so as to move
said clamping piece into a position of repose so that said first surface of said
clamping piece presses against the saw blade; and
a second spring acting on said clamping piece so as to press said
clamping piece against said wedge piece.
Strömberg's invention relates to a device for retaining knife blades for cutting,
perforation or other treatment of a running web, preferably a paper web, whereby the
web runs between a rotatable knife-retaining cylinder and a counter pressure cylinder
knife blade cooperates with a wedge device which is adapted to wedge up the knife
blade in a slot in the knife-retaining cylinder. Thus, the knife blade can be wedged up
by means of the wedge device by being brought into the slot by means of the counter
pressure cylinder. The wedge device cooperates with a height-adjustment device which
is adapted to permit setting of the wedge device at such height in the slot that the
wedge device is able to wedge up a knife blade of a certain defined dimension. The
wedge device comprises two rulers having downwardly inclined wedge surfaces relative
to the slot. The wedge device preferably comprises at least one spring means which is
provided to affect the rulers in vertical direction relative to each other in order to retain
the rulers and the knife blade in the slot until they are wedged up therein.
