A splicing tape management system includes, in executing properly the management of a time limit of a splicing tape, a first storage section configured to store an identification code of a splicing tape for splicing a first carrier tape and a second carrier tape together and a usable time limit of the splicing tape while associating them with each other, and a management section configured to manage the use of the splicing tape based on the identification code and the usable time limit that are stored in the first storage section. The usable time limit is a timing when the use of the splicing tape is to be halted, the timing being determined based on a production time and a usable period after production of the splicing tape or based on a starting time in use and a usable period after starting time of the splicing tape.

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.

When a remaining amount of a sheet on one original sheet roll is equal to or less than a predetermined remaining amount, a pair of holding pads is brought into a first posture where holding surfaces are opened, and the holding surface of one holding pad is pressed to a joining end portion from the outside of the original sheet roll in a radial direction of the other original sheet roll. Further, the holding pad is moved such that the joining end portion is separated toward the outside of the original sheet roll in the radial direction. Further, the posture of the pair of holding pads is changed into a second posture where the holding surfaces approach each other, and the joining end portion is conveyed to a joining part in a state where the joining end portion is sandwiched between the holding surfaces of the pair of holding pads.

A splicing device includes a first detection section which detects whether or not the component storage section protrudes downward from the conveyance reference surface; a second detection section which detects the component storage section of the paper tape; a discrimination section which determines whether a tape inserted into the splicing device is the embossed tape or the paper tape based on a detection signal of the first detection section; a first calculating section which calculates a pitch of the component storage section of the embossed tape by using the first detection section in a case where the embossed tape is determined; and a second calculating section which calculates a pitch of the component storage section of the paper tape by using the second detection section in a case where the paper tape is determined.

A method of joining strip-shaped sheets includes a support step of placing a support member in contact with a reverse feed direction end of a strip-shaped sheet fed to a pressing machine and a feed direction end of a new strip-shaped sheet, and a joining step of joining the new strip-shaped sheet to the strip-shaped sheet by attaching a tape on the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet, wherein in the joining step, the tape is attached from a side opposite the support member with the support member placed in contact with the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet. The problem of the variation in welding quality encountered when welding thin and wide strip-shaped sheets together is resolved and the strip-shaped sheet is fed smoothly.
