The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.

A rotary-tool mandrel for a unit for converting a flat substrate, on which a sleeve (13) is intended to be fitted, the mandrel includes a cylindrical core (14), a peripheral wall (17) that is able to take up a rest position and a locking position by exerting a radial pressure on the sleeve (13) in order to lock it in position on the mandrel (12), a pressure fluid circuit (21) provided between the peripheral wall (17) and the cylindrical core (14) for exerting the radial pressure on the sleeve (13), and a cooling fluid circuit (24) for allowing a fluid to flow in the region of the cylindrical core (14) and for cooling the mandrel (12).

A method of making a preassembled display with automatic stackable supports (PDASS) is described. A PDASS may include two or more blanks (for example pieces of corrugated paperboard) that are joined together, for example to initially form a knocked down flat (KDF). The PDASS may include an insert formed from a single blank, where the single insert blank, when the whole display is erected, automatically erects and provides asymmetric supports that form at opposing corners of the outer blank.

Battery covers and methods for producing battery covers are described. One battery cover described herein includes a single sheet of material formed into a substantially rectangular box shape with an opening formed along one side, the rectangular box shape capable of being folded into a flattened shape for transportation and the material including a flexible laminate of at least one layer of synthetic fiber and a polymer film layer. The material has a thickness and other properties such that when the battery cover is unfolded, the material substantially maintains the rectangular box shape, and when the battery cover is folded into the flattened shape, the material maintains a spring force such that, unless restrained, the battery cover would unfold to the rectangular box shape.

A machine for forming packing templates includes a infeed mechanism that can feed multiple feeds of sheet material into the machine without repositioning the infeed mechanism or forming creases or bends in the sheet material. The machine also includes a separation and cutting systems with one or more cutting tables and biased knives that cut the sheet material packaging templates. The machine also includes creasing roller(s) that forms creases in the sheet material. The machine also includes a system for reducing or eliminating the impact of irregularities in the sheet material.

A rotary-tool sleeve extractor for a unit for converting a flat substrate that includes a base (23) intended to be fixed to the conversion unit (7) and an extraction head (24) that: a) is movable with respect to the base (23) between a withdrawn position and a deployed position and, b) has a gripper (25) that can engage with a sleeve (13) of a rotary tool (10, 11).

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.

A carton for carrying a plurality of articles. The carton has a plurality of panels for at least partially forming an interior of the carton. The plurality of panels includes a top panel, a bottom panel, and at least one side panel. A handle is in at least the top panel. The handle includes a handle feature in the top panel and a flexible handle panel adjacent the handle feature.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. In various aspects the bag can be fabricated from a woven polyethylene layer which can be laminated with a polyethylene film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.
