  • the web segments include a front (101a), a rear (101c) and a mid (101b) portion along the machine direction, i.e. the direction of movement of the web 101. It should be noted, that this orientation does not necessarily need to correspond to the orientation of portions or segments during use, i.e. the longitudinal extension of an article may be such that it corresponds to the machine direction of the web or to the cross-machine direction thereof.
  • the mid portions of the web segments do not necessarily need to be symmetrically centred between the front and the rear portion along a manufacturing direction.
  • the web may be at least one of a single or a composite material of any shape.
  • the web segments may be non-uniform across a width and length with regard to at least one of a thickness, a composition, number of composite layers, densities, basis weights, etc.
  • the web segments may be folded along longitudinal fold lines such as their longitudinal centreline.
  • the roll-up device 106 may be configured as a parallel treatment unit, preferably as a rotatable drum or a turret located between the web supply means 102 and the discharging means 112.

  • the spindles 116A, 118A, 120A, 122A, 124A and 126A also include an attachment means (not shown in the figure).
  • the attachment means is in the form of a fork with a plurality of prongs.
  • the prongs may be used to receive the web segments.

  • the spindles 116A, 118A, 120A, 122A, 124A and 126A may also be translatorily moveable parallel to the machine direction.
  • the spindle When executing the present process and considering the beginning of an rolling- up cycle, the spindle may be positioned close to an upstream (i.e. positioned towards the supply means) separation means (e.g. 126B), which interacts further downstream (i.e. positioned towards the discharge means) with separation means 110, when it makes contact to the web and picks and holds part of the web.

  • the translatory motion of the spindle may advantageously be applied when forming pants-style articles, in particular when articles of varying lengths are to be manufactured without exchanging size parts.
  • the respective parts of the segments or articles may be combined respectively by the combining means 108.
  • the combining means 108 may combine one or more parts (e.g., by gluing) of the respective web segments.

  • the rotational predetermined variable speed of the spindle is preferably adapted such that the trailing segment is kept under essentially constant tension such that the rotational and translatory movement of the spindle are matched to the infeed speed of the web so as to not tear off the leading segment from the trailing segment prior to the optional separation step.
  • the speed of the spindle 118A may be 0 ⁇ v(4) ⁇ v(2) after combining or separation (as shown in the roll-up section 118).
  • the speed of the spindle becomes v(5) ⁇ 0 (as shown for the spindle 120A in the roll-up section 120).

  • the web article may be further rolled-up around the spindle 118 A.
  • the spindle 120A is withdrawn from the web article by a laterally outward movement along or parallel to the rotational axis while the article is being held e.g. by the vacuum belt 112A of the discharging means 112, the belt moving essentially with the speed of the belt contacting surface of the article rolled up in rollup station 120 of rollup device 106.
  • the rolled -up articles may then be discharged from the roll-up device 106.
