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. The stop member obstructs travel by the cutter towards the outside in the radial direction of the rotating member, when the cutter comes in contact with the stop member. The biasing member biases the cutter to the outside in the radial direction of the rotating member and causes the cutter to come in contact with the stop member, by using a predetermined biasing force, and allows the cutter to retreat when the reaction force acting on the cutter is greater than the predetermined biasing force.
