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.

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cutting member from an operating position, in which it is in front of the other cutting member, to an idle position, withdrawn with respect to the feed path of the web material.

An electrode connection cause determination system includes a position measuring instrument. The position measuring instrument is configured to, when an electrode moves between an unwinder and a rewinder in a roll-to-roll state, acquire coordinate value data based on a longitudinal position of the electrode determined according to a rotation amount of the rewinder. The system includes a signal generator configured to generate a connection advance notice signal if the electrode includes a connecting portion corresponding to a cause event, a seam detector configured to detect a seam attached onto the electrode after the connection advance notice signal is generated, and a determination unit configured to, when the seam is detected within a predetermined distance from a first coordinate value of the electrode after the connection advance notice signal is generated, determine that a connection cause of an electrode connection by the seam corresponds to the cause event.

An image recording apparatus, having a conveyer including a pair of conveyer rollers, a recorder, a first sensor, and a controller, is provided. The controller, after a part of an image is recorded on a sheet-formed medium, within a period between a point before the first sensor detects an upstream end of the sheet-formed medium and a point after the first sensor detects the upstream end of the sheet-formed medium, controls the conveyer to convey the sheet-formed medium in a plurality of segmented actions, corrects a conveyance amount to convey the sheet-formed medium after the first sensor detects the upstream end of the sheet-formed medium to a third conveyance amount, which is smaller than the conveyance amount, and after the sheet-formed medium is conveyed by the third conveyance amount, controls the recorder to record another part of the image on the sheet-formed medium.

System for handling cardboard reels to feed machines that produce cardboard tubes, comprising a station (P) for picking up the reels configured to receive a stack (2) of overlapping cardboard reels (1), a station (U) for unwinding of the reels comprising at least one unwinding unit (UU), and handling means (D) for moving the reels (1) along a predetermined path between the reel pick-up station (P) and the unwinding station (U). The reel handling means are provided with an additional reversible device for hooking the reels to the handling means themselves.

An apparatus for generating a roll map of a merge-wound electrode includes a position measurement device configured to acquire coordinate value data for a longitudinal position of an electrode according to an amount of rotation of the rewinder. The apparatus includes an input device configured to input an input signal indicating a start of merge-winding or an end of merge-winding, a seam detector configured to detect a seam, a reference point detector configured to detect a plurality of reference points of the merge-wound electrode, and a roll map generator configured to generate a roll map for simulating the merge-wound electrode moving in a roll-to-roll state based on the input signal of the input device, and to display the longitudinal coordinate values of the electrode, the electrode coordinate values of the seam, and the electrode coordinate values of the plurality of reference points of the merge-wound electrode on the roll map.
