Abstract: An apparatus for bursting perforations on an article, such as a corrugated box, has a rotatable, retractable burst member that exerts an impact force on opposing sides of end portions of the perforated lid. Burst member is arranged for vertical movement towards an end portion of the perforated lid and then rotatable movements to opposing sides of the perforated lid. The article is positioned in a plane substantially perpendicular to the movement of the burst member so that the burst members can engageably contact end portions of the perforated lid with a predetermined impact force. A separator is used to capture the perforated lid and then retract for separating the perforated lid from the main portion of the article.

Abstract: A cutter cleaning apparatus for a filling machine which prevents liquid food adhering to the cutting knife from dirtying cut ends of packaging material. A web-shaped packaging material is continuously sealed in the longitudinal direction thereof to be formed into a tubular shape, a liquid food is charged into the tubular packaging material (11), and the tubular packaging material (11) is nipped from opposite lateral sides at a position below the surface of the liquid food, so that a laterally sealed portion (S) is formed. Subsequently, the laterally sealed portion (S) is cut in order to obtain an original-shape container. The cutter cleaning apparatus includes a cutting knife (21) for cutting the laterally sealed portion (S), and cleaning medium supply means for supplying a cleaning medium to the tip end of the cutting knife (21).

Abstract: This method and apparatus contemplate the making of pocketed springs for mattresses and cushions by inserting compressed springs at intervals along and between the plies of a folder two-ply strip of sheeting, maintaining the springs compressed therein while seaming the edges of the plies to form a sleeve about the compressed springs as the strip is drawn lengthwise toward a release point at which each spring is free to expand to spread the plies. This transposes the edge seaming to mid-height of the spring. A previously made cross seam incorporating the transposed edge seaming limits the forward movement of the spring and a further such cross seam made behind the spring encloses the spring within an individual pocket of the sleeve. The repetition of spring release and cross seaming behind each spring released produces a string or chain of pocketed springs with the closing seam of the sleeve at mid-height of the springs.

Abstract: A pack comprises a horizontal base and vertical side walls formed from a blank. The side walls are joined to each other in planes perpendicular to the base and form stiffening ribs. The side walls are seamlessly joined to the base and the base is seamless. The pack is produced by folding the blank and joining the side walls.

Abstract: The present invention relates to a matrix for the production of a package trough having at least one undercut, consisting of a bottom part, side parts oriented transversely and side parts oriented parallel to the direction of package trough feed, wherein at least one side part oriented parallel to the direction of feed serves as a mold for the undercut, and wherein said side part is fixed in its spatial position in relation to the machine frame whereas the other parts of the matrix can be displaced vertically downwards.

Abstract: A separator finger apparatus and method for insertion of a separation finger into and removal from a stream of web product. The unique motion provided by the elements making up the separation finger apparatus permits the separation finger to be mounted close to folding rolls (from which the web product issues) with reduced separation finger-to-folding roll interference. Specifically, the separation finger is manipulated to rotate and translate simultaneously as it is inserted into or removed from the stream of web product. The elements creating the separation finger motion are preferably a pivot arm mounted for rotation about a first axis and a translation member mounted for rotation about a second axis. The pivot arm is preferably rotatably coupled to the separation finger at a third axis. The separation finger is preferably coupled to the translation member for translational or sliding motion therealong.

Abstract: A method of imparting directional permanency of folding to a sheet, and an apparatus therefor, which is suitable for manufacturing frame bodies, cushioning members and other block products for packaging, from a sheet of paper and other recyclable materials. The method includes a step of moving respective folding working tools, disposed on one or both surfaces of a sheet, required amounts so as to fold the sheet along respective folding ruled lines, and a step of shortening spacings between the respective folding working tools in a uniform ratio in accordance with an apparent amount of shortening in a longitudinal dimension caused by the shifting, while synchronizing with the moving step. Directional permanency of folding can be accurately imparted to the sheet along the folding ruled lines.

Abstract: A sheet feeding, folding and accumulating machine has an integral sheet storing and feeding mechanism, and a plurality of feeding inputs from which sheets are fed to a path of travel through the machine from the sheet storing and feeding mechanism or from an external source.

Abstract: A machine (1) for interfolding sheet material (4a, 4b) starting from a web (3a, 3b) of paper and the like. A sequence of offset sheets (4a, 4b) is formed on folding rollers (7a, 7b) which are counter-rotating with respect to each other and have a plurality of circumferential grooves (15a, 15b), in which oscillating folding arms engage (20a, 20b) so as to form a stack (17) of interfolded sheets (4a, 4b). The folding arms (20a, 20b) have pivots (21) very close to the periphery of the folding rollers (7a, 7b), inside or outside of the grooves (15a, 15b). Moreover they can be operated by a crank mechanism that allows to the grooves (15a, 15b) to be shallow enough also in case of rollers (7a, 7b) of enlarged diameter. For the same reason, the folding arms (20a, 20b) can have a bent portion.
