A roll tensioner for use in maintaining a wrapping material cut edge of a wrapping material retained on a wrapping material roll located within a wrapping material box having an interior cavity with an interior front wall with a top cutting edge. The roll tensioner comprises a thin, flexible main body having distal and proximal end sections separated by a spring back reversion section, and formed having a first side and a second side. Attachment means, preferably an adhesive, is located on at least a portion of the proximal end section on the first side adapted to attach the proximal end section to the interior front wall of the wrapping material box. The spring back reversion section is composed of a material that has an immediate elastic response to a static load and is capable of substantially full recovery when the static load is removed. The distal end mechanically bends downward by way of the spring back reversion section in the interior cavity of the wrapping material box. The distal end section is adapted to rest against the wrapping material proximal to the wrapping material cut edge to retain the wrapping material cut edge in an upward, substantially parallel position to the interior front wall of the wrapping material box for easy grasping of the wrapping material cut edge by an end user.

A printer includes a case including an input port for rolled paper, a cover provided to be rotatable between a closed position of the input port and an open position of the input port, a holding portion that holds the rolled paper, a biasing member that biases the holding portion in a first direction, a stopper mechanism that stops rotation of the holding portion in the first direction, and a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover. When the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member. When the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member.

A magazine unit for a packaging machine comprises a support device configured to rotatably carry a reel of a packaging material web and a reel brake device configured to decelerate rotation of the reel around a central axis. The reel brake device comprises a brake assembly adapted to interact with an outer lateral surface of the reel of the packaging material web and configured to selectively exert a deceleration force on the reel of the packaging material web for decelerating the rotation of the reel around the central axis. The reel brake device comprises a support rail moveably carrying the brake assembly and an actuator device configured to actuate, in use, movement of the brake assembly along the support rail at least towards the outer lateral surface so as to establish contact of at least an interaction element of the brake assembly with the outer lateral surface of the reel.

A dispensing box with a roll tensioner houses a material roll and maintains a material cutting edge in an upward position for easy grasping during use. The roll tensioner comprises distal and proximal end sections with opposing bottom tabs separated by a spring back reversion section. A roll tensioner slide assembly integrated in the front wall of the dispensing box has opposing parallel slits terminating at opposing parallel slots with parallel locking flaps. Opposing bottom tabs of a roll tensioner are inserted through the parallel slots, resting in a first position during non-use and adapted to be slid down into a second position in the parallel slits when later engaged for use to retain the material cut edge in the upward position for easy grasping. The locking flaps have break-away top and bottom walls abutting a bend wall and are in a stored position and later opened outward to a locking position during use to prevent movement of the roll tensioner.

An unpowered, manually operable apparatus for dispensing cushioning wrap material drawn concurrently from a roll of separator material and a self-contained cartridge that includes a roll of expandable sheet material. The rolls are supported on a stand for rotation about respective parallel, spaced-apart axes. In addition to the roll, the cartridge includes a tensioning assembly and support panels that abut respective ends of the roll. The tensioning assembly and the support panels cooperate with the stand to control rotational resistance of the roll. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is manually pulled from the stand with the separator material, and support surfaces on the stand hold the cartridge and the separator roll in position. When the cartridge containing the expandable sheet material is depleted, the cartridge is readily removed and replaced.
