The present invention relates to a method to remove an adhesive label (22) from a bobbin (28), the bobbin including an end portion (24) and an outer surface (25), the method including: providing a bobbin of a coiled sheet closed by an adhesive label positioned on top of the end portion of the coiled sheet (26) to attach the same to the outer surface of the bobbin; locating the adhesive label; applying a sucking force to the location of the adhesive label so as to detach the adhesive label and the end portion of the coiled sheet from the bobbin; and cutting a part of the detached end portion including the adhesive label from the bobbin. The present invention also relates to an apparatus to detach an adhesive label from an end portion of a coiled sheet in a bobbin, the adhesive label being located between the end portion and an outer surface of the bobbin.

Devices, methods, and systems for splicing a trailing edge of an outgoing roll with a leading edge of a replacement roll with a lapless butt splice on-the-fly during converting and printing production. A first strip of adhesive tape may be placed partially under the leading edge, such that a portion of the adhesive tape remains exposed beyond the leading edge. The replacement roll may be accelerated to match the speed of the outgoing web's movement, a trailing edge of the outgoing web may be cut free from the outgoing roll, and the trailing edge of the outgoing roll may be positioned over the exposed portion of the adhesive tape. A second strip of adhesive tape may be applied over the leading edge and trailing edge using a splicer roller timed to apply the tape when the edges pass proximate to the splicer roller.

A device and a method for feeding a sheet material are provided. A conveying machine is disposed above a holding machine. A sensor detects a lateral position of a rubber sheet fed from the holding machine. At a position between a grip position below the conveying machine and a release position at an upstream side in a conveying direction above the conveying machine, a leading edge of the rubber sheet is gripped by a gripping machine. The gripping machine is revolved and moved to the release position using, as a revolution center, a position in a vertical direction midway between the grip position and the release position. The leading edge being released is pressed against a placement surface of the conveying machine by a pressing portion. The rubber sheet is placed on the placement surface and conveyed to a downstream side in the conveying direction by the conveying machine.

Provided is an automatic coiled material switching device, which comprises a machine table (8), a left unwinding device (81), a right unwinding device (82) and a rotatory cutting device (83); wherein the machine table is provided with a left auxiliary roller (84), a right auxiliary roller (85) and a plurality of fixed rollers; the rotary cutting device comprises a bearing seat (1), a bearing (11) arranged on the bearing seat, a rotating main body (2) arranged on the bearing, a rotating mechanism for driving the rotating main body to rotate on the bearing seat, a turning mechanism for driving the bearing seat to turn around, and a driving mechanism; the rotating main body comprises an upper part (21) and a lower part (22); a gap (23) for allowing a material to pass through is formed between the upper part and the lower part; and the rotating body is provided with a pressing mechanism for compressing the material and a cutting mechanism for cutting the material. The automatic coiled material switching device implements the automatic switching of material belts of the left unwinding device and the right unwinding device by arranging the rotating main body, rotating mechanism, the turning mechanism, the driving mechanism, the pressing mechanism and the cutting mechanism.

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.

In a method for removing a wrapping, such as plastic film, from a roll of material an apparatus is used, which has a roll supporting unit, and a cutting means. The roll supporting unit is configured to rotate the roll supported thereon, and the cutting means is movable into cutting abutment against the envelope surface of the supported roll for removal of the wrapping during rotation of the roll.

The invention provides a device for connecting together two flat tubular sheaths, the device including: a blocker (22a, 22b, 22c, 22d) for blocking one end of a first sheath, the blocker having means for opening an end of the first sheath; an adhesive-applicator system for applying adhesive to the inside of the open end of the sheath; the blocker being arranged to authorize closure of the end of the first sheath, once adhesive has been applied thereto, on an end of the second sheath. The invention also provides a corresponding roll of adhesive and a corresponding connection method.
