A cutting apparatus includes a cutting unit that has a spindle with an annular cutting blade mounted to a tip part of the spindle through a blade mount, and a determining unit. The determining unit has a second flow path that is connected to a first flow path in a mounter of the blade mount for causing a negative or positive pressure to act on the first flow path, a measuring device that obtains a measured value of at least one of a pressure and a flow rate in the second flow path, and a screw-engaged state determining section that determines that a screw-engaged state of a fixed nut with a boss section of the mounter where the cutting blade is disposed is defective in a case where the measured value when the negative or positive pressure acts on the first flow path indicates an abnormal value.

Cutter module positioning for full-bleed printing

A printer comprises at least one longitudinal cutter module to cut a print medium in a longitudinal direction with respect to a print media advance direction. The printer comprises a controller to position the longitudinal cutter module along a direction perpendicular to the print media advance direction. The controller is to receive a full-bleed print job and in response to receive print job to position the at least one cutter module along the direction perpendicular to the print media advance direction. The longitudinal cutter module is positioned by the controller to longitudinally cut the print medium.

BI-DIRECTIONAL CUTTING MODULES

According to an example, a cutting module may comprise a carriage and a cutting blade, wherein the carriage may be capable of reciprocating movement along a cutting path. The carriage may be supported by a support structure and the cutting blade may have a fitting pin to engage with the carriage. During a first direction movement along the cutting path, the fitting pin may obtain a first cutting-edge angle. During a second direction movement along the cutting path, the fitting pin may obtain a second cutting-edge angle.

CUTTER MODULE AND METHOD

A cutter arrangement for media processing equipment, including a cutter module to be arranged on a shaft via a dedicated one of a number of transmission devices, at least one of the cutter module and the transmission devices comprising a registration feature to guide a user to arrange the cutter module on the dedicated one of the number of transmission devices.

Method for reducing label waste using a cutting apparatus

A method of reducing label waste that employs a stand-alone or printer attached apparatus for cleanly and efficiently cutting a web of media or tag stock into individual units. The apparatus used by the method may cut vinyl, plastic, or RFID stock material in both back and forth directions without sacrificing cut quality, and preferably comprises a housing, a carriage assembly and a movable cutter assembly. The cutter assembly comprises a cutting element such as a wheel blade, and a pressure adjusting element for adjusting the amount of pressure applied by the cutting element to the stock material. Alternatively, the cutter assembly may be manufactured with a predetermined pressure load, but still permit an operator to adjust the depth of cut. The method involves using the cutting apparatus to make a series of cuts as the label material is incrementally advanced through the cutting apparatus.
