A foil reel mounting device (10; 40) for supporting a reel (2) of stamping foil (3) in a supporting module (1). The device is fixed to the supporting module (1). It includes a support (11; 41) having a recess (16; 46) to receive an axle (7) of the reel (2) of stamping foil (3). A retaining element (12; 42) mounted on the support (11; 41) and arranged to move between a closed position, in which the retaining element (12; 42) retains the axle (7) of the reel (2) in the recess (16; 46), and an open position, in which the retaining element (12; 42) releases the axle (7) of the reel (2) from the recess (16; 46). The retaining element (12; 42) is biased towards the closed position. Also, a supporting module (1) has at least one foil reel mounting device (10; 40) and a stamping machine (100) includes a supporting module (1) or at least one foil reel mounting device (10; 40). A method for loading and unloading a reel (2) of stamping foil (3) with such at least one foil reel mounting device (10; 40) is also disclosed.

A film packing device for a roll of film having or not having a reel includes a handle. Two ends of the handle are provided with a coupling rod and a base, respectively. The coupling rod is provided with a quick-release unit. The base is provided with a limit unit. The quick-release unit and the limit unit are selectively mounted with a first film application unit and a second film application unit. Through the first film application unit, the film packing device can be mounted with a roll of film having a paper reel. Through the second film application unit, the film packing device can be mounted with a roll of film not having a paper reel. The film packing device can be replaced with different types of film in a simple and quick way.

A rolled material dispensing apparatus including a housing, a frame, first and second retention structure, first and second ball bearings, first and second biasing components, and mounting structure. Sides of the frame form an open-front dispensing chamber and include first and second apertures for at least partially receiving the ball bearings therethrough. The retention structure retain the ball bearings and biasing components therein. The ball bearings may be urged out of the way of the roll of material when the roll is loaded into the apparatus. The biasing components urge the ball bearings at least partially through the apertures into ends of the roll when the roll is in a loaded position for retaining the roll in the dispensing chamber.

There is provided a printer including, in a sheet holding section configured to hold roll paper formed by rolling a printing target sheet, a pair of pressing sections configured to hold the roll paper from both side ends, and a holding section provided in each of the pressing section. The holding section is displaceable to a first position where the holding section projects to a side opposed to a side end portion of the roll paper and a second position where the holding section does not project. The holding section enters a cylindrical portion in a rolling center of the roll paper in the first position to hold the roll paper.

A clamping device (1) for receiving and clamping a film roll (2) is described, comprising a winding core (21) and a film reel (22) arranged on the winding core (21), wherein the clamping device (1) can be moved from an open position, in which the film roll (2) can be inserted into the clamping device (1) or removed from the clamping device (1), into a clamping position, in which the film roll (2) is clamped in the clamping device (1). The clamping device (1) comprises a grooved shaft (11) with receiving grooves (11n) arranged in the longitudinal direction offset at the same angular distance, a screw gear formed from a ring nut (12) and a lock nut (14), and clamping levers (16) arranged radially offset at the same angular distance. An output member of the screw gear interacts with the clamping levers (16) such that, when the clamping device (1) is in the clamping position, the clamping levers (16) bear on the base of the grooves (11n) of the grooved shaft (11) and on the inner wall of the winding core (21), forming a clamping force.

A structure of an air-pocket film reel includes a support holder mountable to an air-pocket film machine and an air-pocket film reel mountable to the support holder. The support holder has an end portion including at least one constraint section formed thereon. The air-pocket film reel has an end including an engagement section engageable with and thus mating the constraint section. When the air-pocket film reel is fit to the support holder, the engagement section is put into mating engagement with the constraint section of the support holder to effectively prevent slipping of the air-pocket film reel and achieve synchronous rotation of the support holder and the air-pocket film reel to thereby improve overall productivity, better sealing effect, and enhance stability.
