A rotary tool ejection technology utilizing air to eject contents from the dies of a rotary cylinder. The dies include orifices positioned therein. The orifices are assembled with porous material. The orifices are capable of receiving air from an internal chamber and delivering it to the outer surface of a rotary cylinder. Air is supplied to the internal chamber by an internal shaft. The internal shaft contains a channel in fluid communication with outlets extending radially outward from the channel to locations on the outer surface of the shaft. The shaft is optionally assembled with a manifold having a conduit. The conduit is positioned for intermittent alignment with the orifices in the rotary cylinder as the rotary cylinder rotates relative to the manifold.

Embodiments of the invention provide a die retainer for use in a tool. The die retainer can include a ram head, a release button, and a die pin. The ram head includes a die cavity and a pair of lateral sides on opposing sides of the die cavity. The release button can extend through a release button hole formed in the ram head hand include opposing ends that extend past each of the corresponding pair of lateral sides. The die pin extends through a die pin cavity that intersects the release button hole. The die release button can be actuatable from either of the opposing ends to retract the die pin from the die cavity.

The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut loosely. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

The die-bearing cylinder (1) comprises a surface (3) provided with a plurality of holes (4) internally threaded, said holes (4) presenting a grid arrangement formed by a plurality of rows and lines in the coordinate axes X and Y, and engagement means consisting of a plurality of fastening assemblies (5), each of which having a retractable bolt (7) protruding from the surface of the cylinder (1) defining a geometric center and a geometric axis, wherein a central transverse plane divides the die-holding cylinder into a first half (A) and a second half (B), with the arrangement of the threaded holes (4) and the fastening assemblies (5) in the second half (B) being rotated 180, or being symmetrical, with respect to the arrangement of the threaded holes (4) and the fastening assemblies (5) of the first half (A).

The die-holding cylinder (1) comprises a surface (3) provided with a plurality of holes (4) internally threaded, said holes (4) presenting a grid arrangement formed by a plurality of rows and lines in the coordinate axes X and Y, and engagement means consisting of a plurality of fastening assemblies (5), each of which having a retractable bolt (7) protruding from the surface of the cylinder (1) defining a geometric center and a geometric axis, the bolts (7) being intended to be coupled to dies, wherein the geometric axes of the bolt (7) of the fastening assemblies (5) are positioned in such a way that they are individually distributed between two holes (4) internally threaded and axially aligned on a coordinate axis X that passes through the two holes (4) and at an equidistant distance between said two holes (4).

An automatic die rubber installing machine for a flat die board and an automatic die rubber installing method for a flat die board are provided. The automatic die rubber installing machine for the flat die board includes: a machine table, where an elastic material cutting station and a flat die board placement station are provided on the machine table; an X/Y-axis feeding mechanism provided on the machine table, and located above the elastic material cutting station and the flat die board placement station; a Z-axis feeding mechanism provided on the X/Y-axis feeding mechanism; and an installing work portion provided at a movement output end of the Z-axis feeding mechanism, and facing toward the elastic material cutting station and the flat die board placement station. The installing work portion includes a cutting tool head and a grabbing tool head that are configured to rotate around a Z axis.

The present invention relates to a packaging machine having a thermoforming station, a sealing station and/or a cutting device, wherein at least one of said stations or the cutting device have a lifting table having a lifting device.

A knife cylinder is provided with a restraint parts disposed within a fixation hole; a compression coil spring for pressing the restraint parts inwardly of the fixation hole; an operating parts entering the inside of the restraint parts through a mounting hole; a protrusion provided to the restraint parts; a helical groove provided in the operating parts, the helical groove engaging with the protrusion and being configured so that, when the operating parts rotates, the helical groove can move the restraint parts from a first position to a second position; and a blocking groove provided in the outer surface of the operating parts and blocking the rotation of the operating parts in the reverse direction when the restraint parts is located at the second position.

For precise alignment of the punch stamps relative to the cutting plates, the respective punch stamp is supported in a floating manner, i.e., in a transversely movable manner, on the head plate associated with the punch stamp. The alignment of the cutting edges of the punch stamp with respect to the cutting edges of the cutting plate is accomplished by at least one stamp guide arrangement that is directly active between the punch stamp and the cutting plate and effects precise relative positioning in a direction transverse to the active cutting edges. The centering elements may extend from the punch stamp through the matrix or cutting plate. Alternatively, the centering elements may extend from the cutting plate through the openings of the punch stamp or extend along sliding or positioning surfaces of the punch stamp.

The cylinder comprises a pneumatic system with a plurality of supply branches (A, B, C) provided for pressurized fluid delivery to retractable inserts (A1-A5), (B9-B10) and (C6-C8), such that a supply branch acts on a plurality of retractable inserts present in a first zone (or also referred to in this specification as a group) which is defined by a radial half of the cylindrical body, while a second and third zones of retractable inserts defined by radial portions of the other half of the cylindrical body are fed by supply branches (A, B, C).

It allows air pressure to be applied to the inserts of the two die halves without causing a second, previously fixed tile to fall out undesirably.
