A gripper head adapted to grip, hold and release a piece of cloth, including a first part and a second part with respective conveyor belts, an actuator, such as a hydraulic actuator, a pneumatic actuator or a motor, connected with the second part and configured for turning the second part relative to the first part to apply in a cloth nipping position a first clamping force on a piece of cloth, and a controller connected with the actuator and configured to control the actuator for the second part to selectively apply in a cloth nipping position a second, higher clamping force when the conveyor belts are temporarily stopped with a nipping zone filled by a portion of the piece of cloth.

A sheet discharge apparatus includes: a discharger that discharges a sheet; a loading part on which the sheet discharged from the discharger is loaded; an abutment member that abuts against a rear end of the sheet in a direction of discharging to align the sheet loaded on the loading part; a pull-back member that performs a pull-back operation by contacting with the sheet discharged from the discharger to pull back the sheet toward the abutment member; and a hardware processor that controls the pull-back member. The hardware processor performs the pull-pack operation on a sheet bundle when determining that the sheet bundle bound by a binder is discharged from the discharger.

A mounting member to be mounted on a member that moves in a traveling direction includes: a rectangular sheet member; and an attachment portion having a first surface bonded to one end portion of a reverse surface of a downstream side portion of the sheet member in the traveling direction, the attachment portion being detachably attached to an attachment-receiving portion and having a surface facing a direction different from a direction of the first surface and bonded to the sheet member.
