A bundle breaker including first and second platen assemblies mounted above upstream and downstream breaking supports with first and second actuators for moving the platen assemblies toward and away from the breaking supports and a third actuator for moving the downstream breaking support to perform a breaking operation. The first platen assembly and/or the second platen assembly each includes an upper platen assembly and a lower platen assembly supported by the upper platen assembly, the upper platen assembly including an upper platen and a support for the upper platen and the lower platen assembly including a lower platen supported for movement relative to the upper platen in the vertical direction and relative to the upper platen in the longitudinal direction.

A log saw for cutting convolutely wound logs of web material is disclosed. The log saw includes a cutting blade operating in a cutting plane, a log saw clamp for the retention of a convolutely wound log of web material such that the convolutely wound log of web material extends in a log advancing path through to the cutting plane, and controls connected to the clamping device.

A bundle breaker has upstream and downstream breaking supports each having an input end and an output end. A first platen is located above the upstream breaking support, and a second platen is located above the downstream breaking support, and each platen has an actuator for moving the respective platen toward and away from the breaking supports to selectively clamp a log between the platens and the breaking supports. A third actuator is configured to apply a shifting force to the downstream breaking support to shift the input end of the downstream breaking support relative to the output end of the upstream breaking support from a first position toward a second position to break the second portion of the log from the first portion of the log. The first actuator and/or the second actuator and/or the third actuator includes at least one servo motor.

A bundle breaker includes upstream and downstream breaking supports, platens over the breaking supports and actuators for moving the platens toward and away from the breaking supports. Each of the platens includes a plurality of air bladders each having a bottom contact surface facing one of the breaking supports. The actuators move the platens to selectively clamp a log between the bottom contact surfaces of the air bladders and the breaking supports. A third actuator shifts an input end of the downstream breaking support relative to an output end of the upstream breaking support from a first position to a second position to break a first portion of the log from a second portion of the log.

A cutting apparatus includes a holding member disposed at a position opposed to a cutting blade and having an adhesive layer removably holding an object, a pressing unit pressing the object held by the holding member and having a contact portion brought into contact with the object, a region specifying unit specifying a region where an adhesive retention of the adhesive layer is insufficient along a cutting line of the object cut by the blade, and a control unit controlling the pressing unit so that when the object is cut by moving the blade and the holding member holding the object relative to each other, at least either an amount of pressing or a pressing force of the contact portion is changed between a case where the region specified by the region specifying unit is cut and a case where any part other than the specified region is cut.
