摘要： Provided are methods and apparatus for transporting either an entire web or discrete components of disposable products. The invention is a means of conveying the web or diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this. Methods and apparatus are disclosed to provide sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

摘要： A web processing roll for handling a web of material using vacuum is provided. The web processing roll includes a roll body. The roll body defines an outer periphery against which the web of material is held. The roll body defines a vacuum passage. At least one first vacuum hole fluidly connects to the vacuum passage provides vacuum proximate the outer periphery of the roll body to hold the web of material against the outer periphery with vacuum supplied to the at least one first vacuum hole by the vacuum passage. A first flow path of the vacuum hole extends at a first angle that is non-perpendicular to the rotational axis and is directed, at least in part, axially toward one of the first and second ends at the first outlet end of the at least one first vacuum hole.

摘要： To take blanks of sheets for producing laminated glass, from a cutting table, an adjustable takeoff roller onto which the sheet blanks are wound is used. To fix the beginning of the sheet blank to be taken off to the takeoff roller, openings for applying negative pressure are provided in the lateral surface of the takeoff roller. When a sheet blank is taken from the cutting table, the takeoff roller is brought into position at the beginning of the sheet blank to be taken off, the blank is fixed to the takeoff roller and the takeoff roller is then moved along the cutting table while rotating about its own axis, and so the sheet blank is wound up around the lateral surface of the takeoff roller. For laying down the sheet blank onto a glass pane during the production of laminated glass, a correspondingly reversed procedure may be used.

摘要： An intermittent cutting transferring device configured to cut a first web into individual sheets and to intermittently transfer the individual cut sheets onto a second web being continuously fed includes an upper blade roll with a blade and a lower blade roll with an anvil element. The cut sheet is configured to be sucked onto an outer peripheral surface of the lower blade roll at a position where both side edge regions of the cut sheet and a front end region thereof face an edge area of the second region while a remaining region of the cut sheet faces a center area of the second region. A suction holding force in the edge area is stronger than a suction holding force in the center area.

摘要： A vacuum drum assembly for a printing machine has a drum with an array of passageways distributed along its length and around its periphery. The passageways permit air to flow from outside the drum to inside the drum in response to reduced air pressure inside the drum. The assembly also has an array of valve members, each valve member being movable between a closed position in which that valve member restricts at least one of the passageways and an open position in which the restriction of that passageway or those passageways is reduced. The assembly is arranged such that, when a partial area of the drum is wrapped with a sheet of material, at least some of the valves for the passageways adjacent the edges of that area are open, and the valves for the passageways which are not covered by the sheet and are not adjacent the edges of that area are closed.

摘要： A vacuum holddown for sheet materials has a surface having a field of vacuum ports in which each individual port is gated. When a vacuum is applied to the underside of the holddown, the gates close. When a sheet of material is introduced onto a region of the field, the gates only within vacuum manifold passageway covered by the material are configured to spring open, applying a suction force to the sheet via the now opened ports. The holddown thus automatically adjusts to material size. An implementation for use in an ink-jet printer with cut-sheet print media is demonstrated.

摘要： A sheet suction device includes a sheet bearer having a plurality of suction holes, a suction unit, a first member, and a second member. The first member has grooves arranged in a radial direction, and each of the grooves extends in a circumferential direction. The second member has a plurality of hole rows including a plurality of holes. The plurality of holes in each of the plurality of hole rows is arranged in the circumferential direction, and the plurality of hole rows is arranged in the radial direction. When the first member rotates with respect to the second member, the number of holes communicating with the grooves is changed to change the number of the plurality of suction holes communicating with the suction unit. The plurality of holes includes two or more holes that simultaneously communicate with the suction unit when the first member rotates by a unit rotation amount.
