To provide a foldable structure to which stiffness is imparted so that non-uniform extension and contraction is inhibited even when each surface is formed of a flexible material, a manufacturing method and a manufacturing device of the foldable structure, and a non-transitory computer-readable computer medium storing a program. A foldable structure including at least two tubular structures in which the two tubular structures include a shared surface array which is continuous shared surfaces shared by each other, and a twisting characteristic in the shared surface array of one tubular structure is in a direction opposite to that of the twisting characteristic in the shared surface array of the other tubular structure.

A corrugated display sign with a main body having an inner surface and an outer surface, with the body including a first portion and a second portion. The sign further includes at least one or more formers, and in some embodiments two or more formers, secured to the first portion of the inner surface of the main body, with the formers each including a tab section that secures the former to the main body, a front body portion with a wing portion, and a back body portion with a wing portion. Further, the second portion of the main body is folded around the first portion and the formers, so as to create an elongated elliptical shape for the sign. The display sign is capable of being erected from a knockdown configuration to an erected configuration by folding the former body portions and the wing, and folding the second portion of the main body around the first portion and the formers.

A bale of stock packaging material includes a continuous tube of paperboard material, the continuous tube of paperboard material being flattened and folded back and forth on itself into a fan-folded bale. The continuous tube of paperboard can be a single piece of paperboard with two opposed edges that are folded to overlap with each other. The paperboard material can include a corrugated layer. The opposed edges can be adhered together to form a single seam that runs lengthwise along the continuous tube of paperboard. The adhesive can be applied between the two edges which can join to form the single seam.

The present invention provides a self-standing paper product and a method for manufacturing the same. The manufacturing method at least includes: a step of forming a primary separating fold line, a step of forming a left vertical separating fold line, a right vertical separating fold line, a left horizontal separating fold line and/or a right horizontal separating fold line, and a step of erection and formation. A primary separating fold line, the left vertical separating fold line, the left horizontal separating fold line, the right vertical separating fold line, and the right horizontal separating fold line are formed on a single paper card for separation into a plurality of front presentation regions and folding regions, and the fold lines are then respectively folded to erect and form the regions, so as to form a self-standing paper product that at least includes a front presentation portion and a folding portion.

A container includes a plurality of panels connected together at fold lines configured for extending at least partially around an interior space, where the plurality of panels includes a shelf panel defining at least one shelf flap, a first side panel, a back panel, and a second side panel. The container includes a support panel defining at least one shelf support flap. The shelf support flap is operatively connected the shelf flap of the shelf panel, and is configured to move between a first position and a second position when the shelf flap of the shelf panel is folded. A blank for a container includes a plurality of panels connected together at fold lines configured to be folded at least partially around an interior space, including a back panel. The blank includes a support panel. The support panel is connected to the back panel along a break line.

The invention relates to a method for producing a cushioning product (88), comprising the following steps: providing a flat, longitudinal, two- or multilayered paper strip (10), wherein the individual layers (12, 14) of the paper strip (10) are connected to one another in at least some sections in a middle area (18) extending in the longitudinal direction, and wherein the individual layers (12, 14) of the paper strip (10) comprise marginal areas (20, 21, 22, 23) which are not connected to one another, opening adjacent marginal areas (20, 21, 22, 23) to form a paper strip (10) having a star-shaped cross section, and crumpling the paper strip (10) along the middle area (18).
