A clasp is configured to engage an end of a tube. The clasp has a shaft that is insertable into a tube. The clasp includes a housing with clamping blocks that are spaced circumferentially around the shaft. The clamping blocks are moveable between a disengaged position in which the clamping blocks are spaced radially outwardly from the shaft at a distance sufficient such that a tube is insertable between the shaft and the clamping blocks, and an engaged position in which the clamping blocks are positioned radially inward of the disengaged position toward the shaft and are configured to press a tube disposed between the blocks and the shaft against the shaft. The clasp has at least one actuator engageable with at least one clamping block of the plurality of clamping blocks to move the at least one clamping block between the disengaged position and the engaged position.

A method of forming a roll of convolutely wound web material. The method includes applying adhesive to an elongated mandrel, winding web material around the mandrel to form a roll of convolutely wound web material, rotating the mandrel relative to the roll to smear the adhesive, and removing the mandrel from the roll. The smearing can be in a circumferential direction. The adhesive can be applied longitudinally along the mandrel. The adhesive preferably has a viscosity within the range of 3000 to 18,000 cps. Preferably, the method includes pulling the mandrel longitudinally before the step of removing the mandrel from the roll. The pulling can reduce the mandrel diameter and/or can increase its length. The rotating can be conducted before the pulling, during the pulling or during the winding. The rotating can be conducted before or during the removing. The web material can be bathroom tissue or kitchen towel.

The present invention discloses a tape dispenser which includes a body having a downward facing concave space at a bottom thereof, a cutting blade mounted to the body and positioned in the concave space with an cutting edge recessed in the concave space, a groove member being able to move vertically between a first and second location, at the first location, the groove member being partially submerged in the concave space and pocketing at least a portion the cutting blade for cutting a piece of tape, at the second location, the groove member being downwardly away from the bottom of the body for threading a piece of tape through a gap formed between the groove member and the bottom of the body, a side plate attached to an end of the groove member, the side plate being slidably accommodated in a hollowed space formed inside the body, the side plate having a slot for retaining a spring to urge the side plate to slide downwardly resulting in the groove member to move from the first location to the second location, and a stopper situated within the slot and at an upper end of the spring, the stopper being fixed to the body and preventing the side plate from being completely pulled out of the hollowed space.

A method of forming a roll of convolutely wound web material. The method includes winding web material around an elongated mandrel to form a roll of convolutely wound web material. The mandrel is substantially axially elastic and formed of material having a tensile yield strength divided by elastic modulus greater than 2.0%, and more preferably 2.5%. The mandrel is preferably radially complaint. The method further includes removing the mandrel from the roll. A further method includes winding web material around an elongated mandrel to form a roll of convolutely wound web material, the mandrel being comprised of material having a tensile yield strength divided by elastic modulus greater than 2.0%, and then longitudinally elongating the mandrel.

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 method for extracting a core (1) from a reel (2) of paper is described, where the reel (1) has been wound in a winding station upstream of an extraction station (100) of the core (1); the method comprises the steps of providing an extraction element (3) having an expandable element (4), shaped to enter, when in the non-expanded form, within a cavity (5) defined by the inner wall (6) of the core (1) of the reel (2), the core (1) extends according to a central axis (X) which is substantially horizontal when the reel (2) is positioned for extraction; inserting the expandable element (4) of the extraction element (3) in the cavity (5) of the core (1) on which a roll of paper (20) is wound; expanding the expandable element (4) until it engages the inner wall (6) of the core (1); pulling the extraction element (3) in the opposite direction to that of insertion, to extract the core (1) from the reel (2); bring the expandable element (4) back to the non-expanded form; extracting the expandable element (4) from the core (1). A machine (10) for extracting a core (1) from a reel (2) of paper by means of such method and an extraction station (100) for extracting a core (1) from a reel (2) of paper comprising such machine (10) are further described.

A tape releasing device includes a reel support section and a release section. The reel support section is configured to support a reel in which an outer peripheral portion of a spiral tape, where a carrier tape, in which a cover tape that closes an accommodation section that accommodates an electronic component is attached to a base tape provided with the accommodation section, is spirally wound, and a tip end portion of the cover tape are fixed by a fixing tape. The release section releases the fixing tape of the reel supported by the reel support section.
