The apparatus for winding at lest one web (1), on a winding roll (2), comprises at least a first roll (3), a second roll (4) and a third roll (5) parallel to one another and to said winding roll (2), said apparatus having a nominal winding position in which: a driving torque is applied to at least one of rolls (39, (4) and (5) as to rotate in the direction of said web (1) in order to compensate for the rolling resistance of said apparatus.

A punching station for a web includes a web transport system that operates to advance the web in a first direction at a first rate. A clamp intermittently grips a portion of the web to advance the portion in the first direction at a second rate. A punch is coupled to the clamp such that the punch moves in the first direction together with the clamp. A punch block cooperates with the punch. The punch block is coupled to the clamp such that the punch block moves in the first direction in unison wi...

Composite webs having one or more polymeric structures located on a substrate, closure systems comprising composite webs, and methods of attaching articles are disclosed. The polymeric structures are formed using thermoplastic compositions and are attached to a surface of a substrate. The polymeric structures include an area that is attached to the substrate and a detached area that is not attached to a surface of a substrate.

Device for continuous winding of webs onto winding shafts or winding cores to winding rollers, with a pressure roller supported in a frame that can be engaged on the winding shaft or winding core. This engagement is effected with limited friction and in a sensitive manner by means of a drive, with the pressure roller being supported on at least one steering rod that is pivot-connected to two guides, the other ends of which are pivot-supported in the frame.

A device for winding film webs, paper webs and similar material webs supplied continuously across guide rollers has a counter roller in a device frame part for supplying the material web. A winding shaft that is rotatable and movably supported in the frame cooperates circumferentially with the counter roller, wherein the winding shaft is provided with a corresponding winding drive for continuous winding of the material web onto a winding sleeve. According to the invention, for supporting the win...

The present invention discloses a process and a method providing a high bulk tissue which is both strong and soft. Specifically, it has been discovered that certain low pressure printing technologies may be used to deliver a bonding material to the surface of a high bulk paper web such as an uncreped, through-dried web. The bonding material may be applied to the web either before, during or after the web is softened with a mechanical straining process which will decrease the web bulk by no more ...

The invention relates to an illuminating station for the production of partially designed areas in one or more layers of a web of sheeting and to optically variable elements produced with such an illuminating station and possessing partially designed areas showing different optical properties. The illuminating station has one or more radiation sources for illuminating the sheeting. The illuminating station has, further, a masking tape having partially designed areas showing different optical pro...

The invention relates to the chopping of thin webs, and notably to the chopping of edges trims of thin webs. It proposes a chopping device for thin webs, comprising an input section (10) for receiving the web to be chopped; an accelerating section (18) for accelerating the front end of the web received from the input section. Preferably, the device also comprises at least one puncturing means or knife (13) located between the input section and the accelerating section. The invention also relates...

A device for continuous winding of webs on winding shafts onto winding rollers consisting of arms supporting the winding shaft, a pressure roller that can be engaged on the winding shaft or winding core, a knife separating the web during the roller change, and of a charging electrode supplying the web start with an electrostatic charge, which attaches the web start, newly formed by the web cut, on the winding shaft. In order to always maintain the correct equal distance to the web supplied with ...

Multiple component meltblown webs are disclosed in which the meltblown fibers include an ionomer on at least a portion of the peripheral surface thereof. The meltblown webs are especially useful in dust wipe applications.
