A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.

A magazine has a generally rectangular form of a frame. The frame has two spaced apart caps, at least one rail fixed to the caps so that the rail does not rotate, at least one tube rotatably connected between the caps and parallel to a rail, at least two finger assemblies upon a tube, a cutter that slides upon a rail, connectors and knobs upon each tube allowing it to rotate. The tube receiving a roll of wrapping paper upon its length and over the finger assemblies. The finger assemblies deflecting their fingers inside the roll. The connectors being of two severable components allowing detachment of a tube from a cap to receive a roll. The preferred embodiment has two rails and three tubes forming the frame.

An article of jewelry includes a housing divided into upper and lower portions. The housing can be moveable between an open configuration and a closed configuration. The housing can include therein a post on which a reel assembly including a paper roll can be assembled. One end of the paper roll can be extended through a nonlinear paper slot in an outer wall of the housing. The paper roll can include a plurality of printed messages, stickers, or other designs thereon. The nonlinear paper slot can provide tension to maintain the end of the paper roll within the nonlinear paper slot to facilitate tearing off the end of the paper roll.

A conveyor includes: a receiver that detachably receives a roll-like sheet; a conveyance unit that conveys the sheet in a conveyance orientation along a conveyance surface; and a tensioner that applies tension to the sheet at a position upstream of the conveyance unit in the conveyance orientation. The tensioner includes: a frame having a groove pair extending in a first direction along the conveyance orientation; a guide having a curved surface that contacts the sheet and an engagement member pair that engages with the groove pair; a pivoting member that pivots around an axis extending in a second direction orthogonal to the first direction and parallel to the conveyance surface; a transmission member that transmits pivoting of the pivoting member to the guide; and an urging member that applies urging force including a component in the first direction to the guide.

A tension adjuster includes a plurality of drive shafts, a plurality of drive sources to rotate the plurality of drive shafts, and a drive transmitter to transmit rotational drive force of the plurality of drive shafts to a rotary shaft of a conveyance object wound in a roll. The drive transmitter includes a planetary gear mechanism including a sun gear rotated by a first drive shaft of the plurality of drive shafts and a planetary gear carrier rotated by a second drive shaft of the plurality of drive shafts. The planetary gear mechanism attenuates rotational drive force of one of the plurality of drive shafts to transmit the rotational drive force of the first drive shaft to the rotary shaft of the conveyance object, based on a damping ratio defined by a number of rotations of the sun gear and a number of rotations of the planet gear carrier.

A device for dispensing adhesive tape or for dispensing medical products stored on a roll, that includes a base plate, fitted with a pin upon which a roll or adhesive tape is attached, and a tearing section with a tearing blade spaced at a distance from the pin. The base plate is associated with a fastening section for partially gripping a rod or a bar. The fastening section includes an arm connected to the base plate and that merges with a crosspiece. The crosspiece is fixed to a free arm such that the rod or the bar can be accommodated between the free arm and the connected arm. Also included is at least one fastening unit that is provided to join the connected arm to the free arm.

A sheet feeding device includes a support that detachably supports a roll, a rotation driver that rotates a spool, a guide including a facing portion and a guide portion, a support shaft that swingably supports the guide, a biasing member that presses the guide, a sensor that retractably projects from the facing portion and outputs a detection signal, a roller that contacts an outer circumferential surface of the roll, and circuitry that controls the rotation driver. The circuitry determines a passing time based on a first change rate and a second change rate, and causes the rotation driver to rotate the spool by a predetermined angle in a winding direction, from the passing time, to position a leading end of a continuous sheet at a feeding start position, and rotates the spool in the feeding direction to feed the continuous sheet from the feeding start position along the guide portion.

A conveyance apparatus includes a conveyance unit, a first storage unit, a second storage unit, a measurement unit, and a determination unit. The conveyance unit conveys paper. The first storage unit stores a width of standard paper. The width of the standard paper is a length in a direction crossing a conveyance direction of the paper conveyed by the conveyance unit. The second storage unit stores a user-registered paper width which is different from the width of the standard paper. The user-registered paper width is input by a user. The measurement unit measures a width of the paper. The determination unit determines, based on the measured width and the paper widths stored in the first storage unit and the second storage unit, a width to serve as the measured width.

An assembly is disclosed. The assembly has an adhesive layer, a protective film layer that is fused to a first side of the adhesive layer along a first length, and a cover layer that is fused to a second side of the adhesive layer along a second length. The first length is longer than the second length. The adhesive layer is wound in a roll. The second side of the adhesive layer faces outwardly from a center of the roll.
