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.

Die Erfindung betrifft eine Falzmaschinc zum Falzen von Bogen (6) aus Papier, Pappe und dergleichen mit einem Anleger, mindestens einer Falzstation, einem zwischen Anleger und der Falzstation angeordneten Ausrichttisch, mit einem Ausleger und einer Maschinensteuerung. Der Anleger weist blasluftunterstütze Mittel (7, 11) zum Vereinzeln von Bogen (6) und saugluftunterstützte Mittel (5) zum Übergeben von Bogen (6) an den Ausrichttisch auf. Die Falzmaschine besitzt erfindungsgemäß mindestens eine Einrichtung zur Erzeugung von Blasluft (1) mit geringem Luftdruck und hoher Luftmenge, und mindestens eine Einrichtung zur Erzeugung von Saugluft (2) mit hohem Luftdruck und geringer Luftmenge, wobei die Einrichtungen zur Erzeugung von Blasluft (1) und Saugluft (2) separat ansteuerbar sind.

A sheet surface detecting mechanism (49), which detects the upper surface of sheets stacked on a tray (12), including: a sensor (54,55) disposed in a position spaced apart from a conveying portion (50A); a pivotal sensor flag (52) turning the sensor (54,55) ON/OFF; and a sheet surface detecting member (61) being disposed in parallel with the sheets stacked on the tray (12), moving in a vertical direction while causing the sensor flag (52) to pivot in contact with the upper surface of the sheets, and turning the sensor (54,55) ON/OFF via the sensor flag (52).
摘要:
An arrangement (100) for handling flat elements (202), in particular paper elements (202). A guiding structure (101) is provided, along which a flat element (202) is guidable and transportable along a transport direction (T). A hold-down element (102) is coupled to the guiding structure (101) for holding down the flat element (202) to the guiding structure (101). The hold-down element (102) has a support section (103) on which the flat element (202) is supportable. The hold-down element (102) extends along an extending direction (116) having a component perpendicular to the transport direction (T), wherein suction holes (104) are arranged along the extending direction (116). A suction unit (110) includes a suction opening (111) coupled to the suction holes (104) of the hold-down element (102), an air inlet (112) and an air outlet (113), wherein the suction unit (110) directs air from the air inlet (112) to the air outlet (113) for generating an air flow (114). The suction opening (111) is formed and arranged such that the air flow (114) passes the suction opening (111) so that air flow (114) entrains air through the suction opening (111).

According to the sheet carrying device of the present invention, the controlling unit changes the driving power of the fan driving source, depending on characteristics of the sheet. Therefore, appropriate sucking power can be caused to act, depending on the sort of the carried sheet.
摘要:
Ce dispositif correcteur (1) à rouleaux ou à bande pour l'alignement latéral, en cours de façonnage, d'articles (8) en feuilles ou en plaques partiellement pliés dans une plieuse-colleuse, est constitué d'une structure inférieure (6) au-dessus de laquelle est montée en pivotement dans le plan horizontal une structure supérieure (26). Celle structure supérieure comporte une rangée d'éléments transporteurs (70) qui sont en contact avec la surface plane inférieure des articles (8) et qui sont entraînés par un moyen distinct (87) à vitesse réglable. Le moyen correcteur de ce dispositif est constitué d'un élément de guidage (100) déplaçable parallèlement à un axe (9) matérialisant la ligne virtuelle initiale contre laquelle lesdits articles (8) se sont précédemment appuyés dans leur cheminement amont, avant une opération de rotation effectuée dans un dispositif transporteur (4). Un moyen (110) permet d'appliquer à ces articles, en direction desdits éléments transporteurs (70) constituant une surface perméable à l'air, une pression choisie pour que, ajoutée à la masse spécifique de ces articles, la force de frottement résultante entre les éléments transporteurs (70) et ces articles soit apte à transmettre à chacun d'entre eux une vitesse sensiblement égale à celle des éléments transporteurs quel que soit la masse spécifique de ces articles.
