More particularly, the invention is a single-ply napkin that contains folds running only in the transverse direction of the product, i.e. perpendicular to the length of the napkin.

Abstract: Apparatus and method for conditioning an edge of a sheet to be bound so that the edge is conducive to accepting heat activated adhesives used in conventional binding. The sheet is first bent in one direction to form a folding line, with the fold line being a short distance from the edge of the sheet to be conditioned and with that distance being determined primarily by the thickness of the sheet. The bend in the sheet is typically 90 degrees, with the radii of curvature of the opposite sheet surfaces at the fold line being unequal so that a shear force is applied near the sheet end thereby tending to tear or fracture in interior of the sheet near the end. Typically the sheet is then bent in an opposite direction along the folding line so as to produce an opposite shear force that reinforces the creation of tears and fractured in the sheet.

Abstract: Packaging containers of single-use disposable type which are manufactured from flexible paper/plastic laminate normally display sealing fins (3) which extend over one or more of the walls (2) of the packaging container (1). In parallelepipedic packaging containers, triangular corner flaps (4) moreover occur over which extend the sealing fins (3). The corner flaps are folded down and secured on the final formation of the packaging container against its side wall. This however entails that the material with many times thickness must be double-folded, which entails deformations and stretching which damages the packaging material so that this no longer remains completely liquid-tight and gas-tight. According to the invention, the above-outlined drawbacks may be obviated in that the fibre layer included in the material is heated to a temperature of between 80 and 250° C.

Abstract: A box tube blank having first, second, third, and fourth panels joined together at first, second, third, and forth creases is broken in starting with the blank oriented in a starting plane with the first and third creases superposed and the second and fourth creases outermost. First the second and fourth creases are pressed toward each other parallel to the starting plane to spread the first and third creases away from each other until the second and fourth creases are juxtaposed and the first and third creases lie outermost and the blank lies generally perpendicular to the starting plane. Then the tube blank passes between an upstream pair of parallel rollers extending perpendicular to the starting plane to compress it parallel to the starting plane.

Abstract: Disclosed are carton assembling method and equipment for sucking and taking out flatwise folded cartons one by one from a magazine by means of suction cups, unfolding each carton squarely on a conveyance path while transferring it downward along a rotative path, and supplying the thus-unfolded cartons to an encasing machine by means of a conveyance mechanism. Each carton is held squarely by a pair of stoppers, utilizing its reaction force acting in the returning direction. Thereafter, the carton is reverse-folded against such reaction force and then unfolded again to remove the folding tendency of the carton acting in the folded direction, thereby permitting the carton to hold itself in a square shape. And at the time of reverse folding, the flaps of each carton are expanded so that a contents charging conveyor can be disposed in close proximity to the cartons.

A pair of rollers outside of the tube of material forms the edges of the packaging material into the H-shaped guide to form the corners of the material from which individual filled rectangular packages will be formed.

Abstract: Sheet material (30) is cut into rectangular segments (35). The segments are then moved in sequence parallel to their cut edges (26) rapidly away from the cutting station (34) into a slower operating first sewing station (40) where elastic bands (20, 21) are sewn to the cut head and foot edge portions (26, 27) of the segments. The rapidly moving trailing portion of each segment (35) of sheet material is temporarily accumulated at the accumulation station (39) and progressively fed at a lower rate from the accumulation station to the first sewing station (40). The head and foot edge portions (26, 27) of each segment are folded into overlying relationship with respect to the main body portion by passing the main body portion through a U-shaped turn (49) and at the same time passing the head and foot edge portions through a pair of reverse 90 degree turns (50 and 53).
