A medium supplying apparatus with a detachable rolled medium is provided. In the medium supplying apparatus, the rolled medium is fed to a far side of a setting-and-removing direction of the rolled medium. The medium supplying apparatus includes a plurality of guide members configured to guide the rolled medium when the rolled medium is set. The guide members include at least one contact member which at least partially contacts only a lower outer periphery of the rolled medium and at least one auxiliary member which does not contact the outer periphery of the rolled medium. The contact member and the auxiliary member are connected at a base via the same rotary shaft. The auxiliary member is shorter than the contact member in a medium feeding direction, and is disposed in parallel with the contact member.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

A method for removing outer layer of rollstock includes: first step of cutting rollstock's outermost circumferential film in a first cut portion, the rollstock formed by a film sheet rolled from base end to tip end and the tip end temporarily fixed to an outer circumferential surface; second step of cutting the film in a second cut portion closer to the base end than the first cut portion, a length from the tip end to the second cut portion being equal to or more than one round of the rollstock's outermost circumference; and step of discarding a first cut-film piece from the first cut portion to the tip end and a second cut-film piece from the first cut portion to the second cut portion by drawing the first and second pieces with a drawing device while driving an unwinding roller mounted with a hollow portion of the rollstock to rotate.

A method for cutting at least an outermost film of rollstock across a width direction of a film, the rollstock formed by a film sheet rolled from base end to tip end, the method including: separation step of generating a gap between the inner peripheral film and the outer layer by separating first edge portion of the outer layer from the inner peripheral film in a radial direction of the rollstock, in a state where the outer layer is remained to be rolled as a part of the rollstock; step of displacing a portion of the outer layer defining the gap in a first width direction from the first edge portion to second edge portion in the width direction; and step of cutting the outer layer across the width direction during the displacement step, while the first cutter is moved from the first edge portion to the second edge portion.

Subject matter of the invention is an adhesive tape (K) for on-the-fly roll changeover of flat web material (RB) wound up into rolls (R; B), having a carrier layer (K3), which comprises a first surface (K31) and a second surface (K32) opposite the first surface (K31), a first layer of adhesive (K1), which is disposed indirectly or directly over at least part of the area on the first surface (K31) of the carrier layer (K3), a second layer of adhesive (K2), which is disposed on at least one areal region (FB) of the second surface (K32) of the carrier layer (K3), and at least one predetermined breakage area for the areal splitting of the adhesive tape (K), where the predetermined breakage area is configured such that the at least one areal region (FB) comprises a surface coating (K4), which is disposed between the carrier layer (K3) and the second layer of adhesive (K2), where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of adhesion of the surface coating (K4) to the carrier layer (K3), and/or where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of cohesion within the surface coating (K4), wherein the second layer of adhesive (K2) has a deactivated bonding region (K6) on a surface (K21) pointing in the carrier layer (K3) direction.

A sheet delivery system includes: a joining unit configured to join, to an intermediate section of a sheet being delivered from a delivery-side original material roll, an end section of a sheet of a standby-side original material roll; and an operation robot configured to retrieve the end section of the sheet from the standby-side original material roll and convey the end section of the sheet to the joining unit. The sheet delivery system is configured to set, in advance, a sheet retrieval position at which the sheet is retrieved from each of the original material rolls, for each of the original material rolls. The operation robot is configured to convey the end section of the sheet from each of the sheet retrieval positions to the joining unit.

Techniques for processing a web with a laser are provided. In an example, an apparatus for processing web material can include multiple processing stages and a laser assembly. Each of the multiple processing stages can be configured to process a moving web of material along a web path. The laser assembly can be configured to process the moving web of material with a laser at a first stage of the multiple stages. The laser assembly can include a laser configured to generate a laser beam, a gimble assembly configured to direct the laser beam along a cut path at a position of a web path of the moving web of material, and a servo driven mirror assembly configured to provide an adjustable field of view for the laser stage at the position of the web path.

A sheet feeding device includes a sensor, a roller, and a support on which the sensor and the roller are disposed. The support supports the sensor and the roller so that the sensor and the roller contact a surface of the sheet roll. The sensor and the roller face toward an axial center of the sheet roll. The roller is spaced apart from the sensor in a circumferential direction of the sheet roll. The sensor has a detection accuracy capable of detecting a step at a leading end of the sheet roll.
