Methods and apparatus for stripping away portions of substrate are disclosed herein. In some embodiments, a flexible and/or soft impact-element(s) rotates around a rotation axis to drive a peripheral portion across a substrate plane of the substrate and/or to repeatedly collide with the substrate. At least some of the collisions are effective to partially dislodge or to strip away portion(s) of substrate.

A sheet processing apparatus includes a conveyance portion, a punching portion, a moving portion, a first detecting portion, and a control unit configured to control the conveyance portion, the punching portion and the moving portion, wherein the control unit is configured, for a target position of each of a plurality of holes to be formed to a single sheet, to cause the first detecting portion to execute a detection process, and to execute a moving process of moving the moving portion based on the output value of the first detecting portion corresponding to the target position and a punching process of performing punching to the target position of the sheet by the punching portion after the moving process has been completed.

A sheet processing apparatus includes a conveyance unit, a punch member configured to be rotatably supported and punch a hole at a predetermined position, a sensor, a driving source configured to rotatably drive the punch member, and a control unit configured to control the driving source. The control unit is configured to (1) control the driving source based on a punching gap distance between a last punching position of a preceding sheet and a first punching position of a succeeding sheet in the sheet conveyance direction, and a rotational position of the punch member, and (2) perform an avoidance process of avoiding a punching process of punching the hole in the succeeding sheet in a case where the control unit judges not to perform the punching process in the succeeding sheet when the succeeding sheet has reached the detection position.

Examples of print media cutting procedures and devices are described. The print media is cut with a first cutting module while the print medium is advanced through the device. The print media is then reversed before being cut with a second cutting module. The first cutting module can be moved laterally at the same time as the print medium is moved in the reverse direction.

An automatic device for emptying bags of frozen blood product includes a product removal device, a product reception hopper, a transporter for transporting the bag from a reception area to the product removal device, and at least one cutter located in the path of the bag between the reception area and the product removal device. The at least one cutter is housed in a support configured to oscillate for absorbing energy of impacts of the bag against the cutter and to return the cutter to its initial position.
