  2. Roll slitting - Wikipedia

    en.wikipedia.org/wiki/Roll_slitting

    Roll slitting is a shearing operation that cuts a large roll of material into narrower rolls. There are two types of slitting: log slitting and rewind slitting . In log slitting the roll of material is treated as a whole (the 'log') and one or more slices are taken from it without an unrolling/re-reeling process.

    In addition to purchasing equipment, leasing options are often attractive. [6] Machinery must be compatible with the expected operating conditions. For example, cold temperature operations require special considerations. [7] Some industries must perform periodic washdowns of all equipment. This high pressure chemical washing puts special ...

    en.wikipedia.org/wiki/Converter_(industry)

    Both print processes are suited to high speed roll-to-roll processing. [citation needed] Many converting companies will process large diameter, wide rolls of material as this increases the converting efficiency by minimising changes. On completion of the converting process the rolls may be cut into smaller rolls on a slitting machine or a ...

  5. Slot-die coating - Wikipedia

    en.wikipedia.org/wiki/Slot-die_coating

    Both industrial roll-to-roll and sheet-to-sheet systems typically feature slot-dies in the range of 300 to 1000 mm in coating width, though slot-dies up to 4000 mm wide have been reported. Commercial slot-die systems are claimed to operate at speeds up to several hundred square meters per minute, [ 14 ] with roll-to-roll systems typically ...

  6. Cutting stock problem - Wikipedia

    en.wikipedia.org/wiki/Cutting_stock_problem

    Industrial applications of cutting-stock problems for high production volumes arise especially when basic material is produced in large rolls that are further cut into smaller units (see roll slitting). This is done e.g. in paper and plastic film industries but also in production of flat metals like steel or brass.

    An example of one of these machines is a slitting machine or slitter rewinder which is used to cut or slit large rolls of material into smaller rollers. Airshaft winding a plastic film. Air shaft is a machine part or shaft which tightens the core or roll on filling air. Air Shafts are of two types:

  8. Orbital stretch wrapper - Wikipedia

    en.wikipedia.org/wiki/Orbital_stretch_wrapper

    An orbital stretch wrapper. An orbital stretch wrapper is a means of applying stretchable plastic film to a load, consisting of a roll (or rolls) of stretch wrap supported on a vertical rotating ring and a means of passing a load through the ring's eye horizontally.
