Abstract: In a web cutting device, a web held by pads has a section between mutually adjacent pads that is sandwiched between an anvil and a blade edge of a cutter and cut. A stop member is fixed in a rotating member. The cutter is biased by a biasing member and comes in contact with the stop member.
