A machine produces foam-in-bag from foam precursors mixed within the bag. The machine comprises a base and a shell. The base and shell are moveable relative each other between a base/shell disengaged position and a base/shell engaged position. In the base/shell engaged position, the base and shell divide the bag so that a mixing chamber is isolated from the remainder portion of the bag. First and second nozzles inject foam precursors into the mixing chamber. A mixer engages the mixing chamber to provide mixing energy to facilitate the foam reaction.

The invention is an under-filled cushion detector that is capable of conveying a string of packaging cushions and detecting whether the string of packaging cushions may be under-filled. The detector includes an upper driven belt that is movably suspended above a lower belt. The belts cooperate together to define a longitudinal cushion pathway between the belts. The distance between the upper and lower belts may vary depending upon the thickness of the string of packaging cushions. If a string of under-filled cushions travels between the upper and lower belts, the upper belt can move downwardly in the direction of the lower belt. A switch stops the upper and lower belts if the height of the cushion pathway decreases below a predetermined threshold. The detector can be used in a system for manufacturing and transporting packaging cushions to a desired location.

A winding device generally includes a spool, which includes a shaft, a sleeve rotatably coupled to the shaft such that the sleeve and the shaft are capable of partial independent rotation relative to one another, with the sleeve adapted to receive thereon a core onto which a web of material may be wound, and one or more gripping members, which are adapted to engage the core upon relative rotation of the shaft in a first direction, and disengage the core upon relative rotation of the shaft in a second direction.

A method comprises pulling a continuous web to advance the web along a path of conveyance and to create tension in a lengthwise portion of the web; manipulating the web to cause the portion of the web at a point along the path to have a non-uniform tension across the width of the web, with a maximum tension being at a location spaced from the first longitudinal edge of the web, and with the tension decreasing from such location toward the first longitudinal edge of the web such that a zone in the web at the first longitudinal edge has reduced tension; and controlling transverse positioning of the first longitudinal edge in the zone of reduced tension. The reduced-tension zone is produced by a tension-reducing member about which the web is pulled.

A molding apparatus for making a continuous molded article generally includes a pair of spaced-apart molding assemblies, which cooperatively generate a movable mold having a dynamic mold-cavity therein, each of the molding assemblies including a series of movable mold segments, which are adapted to fit together to form a portion of the dynamic mold-cavity, a drive mechanism for conveying the mold segments along a path, and a dispenser for dispensing a moldable, expandable material into the dynamic mold-cavity.
