Web-wound rolls with a web edge treatment with microspheres and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more stripes of coated material are disposed adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the one or more stripes of coated material.

A method of estimating a volume of a remaining fluidum in a non-translucent recipient having an opening which area is wider than or equal to the area of a bottom of the recipient. The method includes taking a picture of the opening at the top side of the recipient by with camera, deriving from the picture characteristics of a first and second number of pixels representing a visible part of the recipient and a visible part of the fluidum in the recipient, respectively, requesting from a user an identification of the recipient, matching the identification with a stored identification in order to retrieve reference data about an empty recipient, and estimating a volume of the remaining fluidum in the recipient by means of the retrieved reference data and a ratio of the characteristics of the first number of pixels and the characteristics of the second number of pixels.

A tearable core, adapted for winding a sheet product, includes a cylindrical body wall defining a longitudinal hole of longitudinal axis XX′. The cylindrical body wall is tearable from an edge, and includes an outer strip and an inner strip that are helically wound on one another and displacedly overlapped in a lateral direction parallel to the longitudinal axis XX′, and secured together through their mutually facing surfaces by a first region of attachment. The strips are made of the material having characteristics such that the inner strip and the outer strip are made of cardboard having different water drops. The cylindrical body wall is formed by securing together the outer strip, a first end part of the outer strip of one turn being superposed and secured to a second end part of the outer strip of an adjacent turn through their mutually facing surfaces by a second region of attachment.

An architectural covering and a method of manufacturing the covering is provided. The panel may include multiple strips of material extending lengthwise across a width dimension of the panel. The strips of material may be overlapped and coupled to one another to define cells between adjacent strips of material. The panel may be retracted and extended across an architectural opening, and the strips of material may include a resilient support member to expand the cells as the panel is extended across the architectural opening. The panel may be manufactured by helically winding a continuous, elongate strip of material about a drum in an overlapped manner.

The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.
