The invention is directed to method and system for folding pads. In one aspect, the system includes a conveyor for conveying a series of pads, one after another, to a folding station. A folding apparatus at the folding station folds each pad along said major axis as the pad is conveyed in a forward direction. The folding apparatus includes a hold-down member adapted to contact a center section of each pad extending generally parallel to said major axis as the pad is conveyed forward. The folding apparatus also includes a pair of folders on opposite sides of the hold-down member adapted to contact side sections of the pad on opposite sides of said major axis as the pad is fed forward and as it is held down by the hold-down member to fold the side sections of the pad to positions facing one another. The pads may be used as feminine protection pads.

Pad folding system and method

The invention is directed to method and apparatus for blending fibers. In one aspect, the apparatus comprises blending apparatus for blending fibers of different materials, at least one of which is absorbent, and for conveying the blended fibers to a fiber collection station. A first weighing apparatus weighs out a first quantity of first fibers at a first weigh station. A second weighing apparatus weighs out a quantity of second fibers at a second weigh station. The first and second quantities of fibers are conveyed to a blend opener having a beater roll rotatable in the blend opener. The beater roll opens and mixes the fibers. The fibers are entrained in an air stream by a pneumatic conveyor system and conveyed to a fine opener. The fine opener has a rotatable clothing roll to further open and mix the fibers. The pneumatic conveyor system is operable to separate fiber fines from longer fibers and to deliver the longer fibers to said fine opener. The blended fibers can be used for making pads, such as feminine protection pads.

Fiber blending apparatus and method

A cutting method and apparatus () includes a rotary cutter () having an axial-direction (), a radial-direction () and a circumferential-direction (). The rotary cutter () includes a rotary shaft member () having an outer peripheral surface (), and at least one knife member () joined to the shaft member (). At least a portion of the knife member () extends axially along the shaft member () and extends radially outward from the shaft member. In a particular feature, at least one peripheral bearing member () and desirably, at least a cooperating pair of peripheral bearing members () can be joined to the rotary shaft member (). At least an operative portion of each peripheral bearing member () extends radially outward from the shaft member () and extends circumferentially about the shaft member.

Cutting method and apparatus having an affixed knife

The invention is directed to method and apparatus for making pads, such as interlabial pads. The apparatus includes a blending apparatus that weighs and blends fibers of different materials, at least one of which is absorbent. The blended fibers are conveyed through a chute to a fiber collection station. At the fiber collection station, collecting and feeding apparatus collects the blended fibers and feeds them to a forming apparatus that forms the blended fibers into a continuous blended-fiber web. The blended-fiber web is fed to a pad-making apparatus that cuts fluid-absorbent bodies in the blended-fiber web and laminates the bodies with at least one continuous cover web to form a laminated web. The laminated web is fed to a sealing and cutting apparatus to make the pads. Folding apparatus is provided for folding each pad along a major axis thereof.

Method and apparatus for making interlabial pads

The invention is directed to method and apparatus for wrapping pads. A web of flexible wrapping material is adapted to be pulled in tension over a forming device. The forming device has first and second folding members having angled folding edges adapted for contact by respective opposite side margins of the web as the web is pulled past the folding edges. A web guide guides the web toward the folding edges. An opening between the web guide and the folding edges is adapted to be spanned by a central portion of the web as the web is pulled past the forming device. A series of pads are conveyed by a conveyor, one after another, and placed on the web as it is pulled past the forming device so that the pads move with the web over the opening and past the folding edges of the forming device. A surface applies a force to the pads to force the pads against the central portion of the web as the pads move across said opening. The force is sufficient to cup the web to position the pads for travel past the first and second folding members with concurrent folding of the side margins of the web by respective folding edges to form a tube around the pads.

Method and apparatus for wrapping pads

An apparatus and method is disclosed for winding a web about a central axis and a rotating mandrel to form a roll. A rolled web product with an alternating winding pattern may be manufactured. A feeding mechanism provides a running web to be wound into a roll. A retainer assembly may be configured for holding the web as it is wound upon the rotating mandrel. The retainer assembly may be configured to accommodate oscillating movement of the rotating mandrel between a clockwise and a counterclockwise direction. The web may be placed upon a roll by winding in one direction and then back again in a second direction repeatedly to form a roll. Retaining means, such as paddles, may be actuated from an active position in contact with the web to a resting position removed from the roll. Paddles may serve to hold the web upon the outer surface of the roll at the time in which the rotating mandrel is changing rotational direction.
