Stock material units that may be used in a dunnage conversion machine. For example, stock material units include sheet material that may be fed into the dunnage conversion machine and may be converted thereby into dunnage.

The invention relates to a method for removing defects on a stationary web of a packaging material (106), comprising moving said web of packaging material (106) through a repair line from a first rotatable roller (121) to a second rotatable roller (122) in a first direction, cutting off said web of packaging material (106) at a first predetermined position, guiding said web of packaging material (106) of said first roller (121) into a second direction, wasting said web of packaging material (106) of said first roller (121) by movement in said second direction to a waste station, cutting off said web of packaging material (106) of said first roller (121) at a second predetermined position, guiding said web of packaging material (106) of said first roller (121) back into said first direction, splicing said web of packaging material (106) of said first roller (121) back together with said web of packaging material (106) of said second roller (122) at said first predetermined position, wherein said method is automated. The invention further relates to a device for removing defects on a stationary web of a packaging material.

Splicing method and unit for a packaging machine, whereby a first film is spliced to a second film which is a spare film. The splicing is performed by means of an adhesive element with two opposing adhesive surfaces, one for each film, and a longitudinal adhering element. First an adhesive surface is adhered to the adhering element and said adhering element moves so that the other adhesive surface comes into contact with the second film and adheres to it. Then the adhering element is separated from said second film, the adhesive element being adhered to said second film, and the first film is caused to come into contact with said adhesive element already adhered to the second film.

To make a tape length that can be supplied at one time long, and to make it possible to directly supply a tape from a record wound tape. A tape supplying method of this invention includes: connecting a tape end to an outer side of one record wound tape of a first record wound tape and a second record wound tape and a tape end to an inner side of another record wound tape, by matching a surface and a rear surface of the tapes; and after the connecting, supplying a tape of the first record wound tape and the second record wound tape from a tape end of the first record wound tape to an opposite side of a side that has been connected to the second record wound tape.

A system is disclosed. The system comprises one or more print controllers to generate print interrupt instructions in response to receiving a web splice signal indicating that a web splice on a web print medium has been detected, wherein the print interrupt instructions indicate a first side sheet image and a second side sheet image within a print job to pause prior to stopping printing, wherein the print interrupt instructions comprise gap instructions to open a first printhead gap at the first print engine and to open a second printhead gap at the second print engine, control printing of the first side sheet image on a first side of a web at a first print engine based on the print interrupt instructions, control printing of the second side sheet image to a second side of the web at a second print engine based on the print interrupt instructions, wherein the print interrupt instructions are generated based on a determination of an interrupted first side sheet image to be paused prior to opening the first printhead gap and a determination of an interrupted second side sheet image to be paused prior to opening the second printhead gap.
