The splicing device for splicing a trailing edge of a first web material to a leading edge of a second web material includes members defining a feed path of the web material. The device also includes a first cutting member and a second cutting member, cooperating with the first cutting member. One of the two cutting members is provided with a movement transverse to the feed path of the web material, to move the cutting member from an operating position, in which it is in front of the other cutting member, to an idle position, withdrawn with respect to the feed path of the web material.

A tape applicator including a housing and an adjustment mechanism. The housing partially defines a cavity. The adjustment mechanism includes a course and an adjustment plate. The course includes a plurality of positions. The adjustment plate is movable along the course among the plurality of positions. The adjustment plate is held in a selected position of the plurality of positions by the housing based on a size of a tape roll configured to be supported in the cavity.

A roll dispenser is arranged to support a roll of packaging material, and includes a chuck assembly with a first chuck unit that includes a first plug received in a first axial end of a core of the roll, a first shaft fixed to the first plug, a first mount brought into engagement with the first shaft, and a first brake connected to the first plug and the first mount to establish friction between the first plug and the first mount. A first handle assembly may adjust a first compressive force applied axially between the first mount and the first shaft to regulate the friction between the first plug and the first mount. The chuck assembly also may include a second chuck unit received in a second axial end of the core for additionally supporting the roll of packaging material.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

A robot system and a method for packaging coils of sheet metal is provided. The method and robot system for coil packaging, having two industrial robots, each robot being provided with a robot arm provides for a solution where the direction of travel along the envelope surface of the coil is inclined relative the rotational axis of the coil, positioning of the roll of wrapping material in three-dimensional along the circumferential edge may be adjusted for each pass and/or where the positioning of the longitudinal axis of the roll or wrapping material is in an inclined angular direction relative the direction of rotation.

A printing device includes a first support portion, a second support portion movable in a moving direction of the second support portion toward and away from the first support portion, a movable probe movably supported by a detector, and a permission mechanism. The movable range consists of a first range and a second range. The permission mechanism is configured to permit the movable probe to move in accordance with the movement of the second support portion in the separating/approaching direction relative to the first support portion in a case where the movement of the second support portion is within the first range, and is also configured to prevent the movable probe from moving irrespective of further movement of the second support portion relative to the first support portion in a case where the movement of the second support portion is within the second range.

A stretch film dispenser with a moving device includes a frame. The frame includes a bottom seat and a coupling seat. A tubular member is connected between the bottom seat and the coupling seat. The tubular member is provided with a telescopic rod. The bottom seat is provided with a moving unit. A bottom surface of the moving unit is provided with at least two first moving members. When in use, the telescopic rod is pulled to a height suitable for holding, and then the user holds the telescopic rod to pull the stretch film dispenser. The stretch film dispenser can be moved through the moving unit, thereby achieving the effect of moving the stretch film dispenser easily and conveniently.

A safety chuck mounted to equipment that process web material is provided. The safety chuck is provided with a die spring connecting a moveable jaw with a spindle, said spring urging the moveable jaw into a fully closed position. A number of magnets mounted on a mounting flange will engage the moveable jaw, overcoming the spring's force and holding the moveable jaw in a fully open position. Rotation of the spindle releases the magnets allowing the spring to force the moveable jaw back into a fully closed position.

A medium supporting device including a support part configured to support a roll body on which a sheet shaped medium is wound, a shaft serving as a rotary axis of the roll body and secured with the support part, and a driver configured to rotate the roll body supported by the support part. The shaft is secured to the support part by using a metal plate having a flat surface provided with an insertion hole, the insertion hole being a hole into which the shaft is inserted. An outer circumference part of the metal plate is restricted from moving in a rotation direction of the roll body relative to an inner circumference part of the support part.

A printer includes two supporters disposed at a storage section, an adjuster movably supporting at least a specific supporter of the two supporters, a protrusion protruding upward from a second section, the second section being an upper portion of the specific supporter, a locking section locking a first section in a position to which the first section is moved via the adjuster, the first section being a lower portion of the specific supporter, and an engagement section having elastically-deformable engagement pieces arranged at intervals in a particular direction intersecting a vertical direction, the protrusion being configured to, when the cover is closed, engage with at least a specific engagement piece from beneath, the specific engagement piece being maintained elastically deformed upward.
