Abstract: A die-cutting blade can form smooth die-cut lines in case-forming blanks which are less likely to injure hands when touched. A strip-plate-shaped steel blade plate has a pair of chamfers formed on opposite side surfaces of the blade plate, respectively, so as to extend from one side edge of the blade plate at substantially equal inclination angles. The chamfers define a cutting edge along the one side edge. The cutting edge has a composite wave pattern formed from a small wave pattern bent to have a wave shape within the range of the thickness of the blade plate, and a large wave pattern formed by a large undulation in the small wavy edge toward opposite side surfaces of the blade plate over its entire length within the range of the thickness of the blade plate, in order to provide smooth die-cut lines.

Abstract: A package of a strip of material has a plurality of parallel side by side stacks each containing a length of the strip which is folded back and forth such that each folded portion of the stack is folded relative to the next portion about a line transverse to the strip. Preferably, the side edges of the strip portions are aligned. The strip can be continuous through each stack and connected by a splice from the end of one stack to beginning of the next stack. To reduce the height of the stacks, the package is compressed and maintained in the compressed condition by, for example, an evacuated sealed bag. The strip of each stack is formed to have a varying width, for example to form diaper inserts when the strip is cut into individual strip elements. The length of each strip portion of the stack is arranged to equal a whole number of strip elements so that the cut lines can be arranged at the fold lines.

Abstract: There is provided a thermoplastic film bag having at least two integral members that facilitate opening the bag. The bag is manufactured from a flattened tube of thermoplastic material which may be distinctively severed along independent phase shifted sinusoidal oscillating paths down the center of the collapsed tube. The bag may have two opposed tie members which are offset from the vertical center axis of the bag and from each other. The tie members may be grasped and pulled apart to facilitate the easy opening of the bag. The tie members may then be tied together to form a strong member by which the bag may be picked up and carried. In alternate embodiments the shape of the integral tie members can be modified to create a bag having only the easy open feature with no tie members. A method for making the bag is also described.

Abstract: A perforating blade and signature having a unitary blade (12) that is very narrow in width in proportion to its length, with a cutting edge (16) along one longitudinal side. The cutting edge (16) comprises a combination of a number of spaced-apart straight (12) and angled (20) sections arranged so that the angled sections (20) angle inwardly toward a center point (18) on the perforating blade and along a single side of the cutting edge only. In one embodiment the pattern starts with a single long cutting tooth in the center (18) of the blade followed outwardly from the center on both sides with a repeating pattern of three angled teeth followed by a short straight tooth and so forth. The angled teeth (20) are all angled to the same side of the blade so that the resulting fold line (26) has cuts only on one side (29) of the fold line. The angled cuts result in ties (28) that twist easily, and that, therefore, result in fold lines (26) that fold cleanly without gusseting or binding.

Abstract: Apparatus for cutting labels from a ribbon on which the labels are printed. The ribbon is fed into the apparatus along a vertical plane, for instance. There are vertically spaced apart knives adjacent the ribbon for cutting the upper and lower contours of the labels from the ribbon. The knives are caused to pivot toward the ribbon and to rise and fall under the influence of a cam that is shaped correspondingly with the desired contours. After the upper and lower contours are formed the ribbon is caused to change direction around a roller while at the same time the trim margin is deflected in another direction and drawn away. The ribbon, with labels still connected endwise is fed over a vacuum cylinder which has cutters at its periphery for separating the labels from a waste portion between them. The labels are removed from the vacuum cylinder and led to a label applying machine, as an example.

Abstract: Polygonally-shaped blanks useful in making products such as can parts are formed by dividing a relatively wide web of material into a plurality of relatively narrow strips, each strip having longitudinal edges delimited by scroll lines formed from a plurality of straight scroll line sections. The strips can be arranged parallel to a longitudinal axis of the web or at an angle relative thereto. It is also possible to divide the strips into individual blanks at a scrolling station or at a remote can making station. The polygonal shape of the blanks permits them to be designed so as to compensate for earing caused by the anisotropy of the material from which the web is made. Various punches and slitting arrangements can be employed to perforate the web and to longitudinally and laterally cut it so as to form the strip and/or blanks therefrom.

Abstract: A rotary notcher is used in a continuous strip processing line for metallic strip to cut out side or edge portions of the joined strips in the welded area. When an arc welder is used, welding may be done only in the center area of the seam remote from where the notching occurs. The rotary notcher is activated in a time relationship with the welding process to notch along the joined seam. The notcher comprises two opposed housings along longitudinal edges of the strip for cantileverly supporting a cooperative pair of rotatable knife drums each having cooperative arcuate surfaces upon which an arcuate knife is mounted, and cooperative flat sections for allowing the strip to travel therebetween without hitting against the drums. The knife has a continuous gradual slope with a desired depth formed between the two extremes of the edge of the knife to effect a smooth continuous cut.
