A method for manufacturing a bag includes a wall of the bag is passed along a placement drum for rotatably mounted handles; a handle is hooked onto the drum, legs of the handle extending backwards along a perimeter of the drum in the direction of rotation of the drum, the legs being connected by a cross member; same is completely turned over using a turnover drum so that the legs are at the front on the placement drum; and the handle is deposited on the wall.

The present disclosure relates to a delivery bag in which the lower end of the bag is closed and wherein said lower end of the bag comprises at least one carrier handle or one carrier loop, and wherein at the same time, the upper end of the bag has a closable first opening for introducing articles for delivery. The present disclosure additionally relates to the use of the delivery bag according to the present disclosure for the transportation of goods for delivery, in particular goods for delivery for mail order and online commerce, as well as a method for producing a delivery bag according to the present disclosure.

A side-gusset bag has front and back face panels each having two longitudinally extending side edges. Two folded side panels are each joined to the face panels at the side edges and each having a center longitudinally extending crease between the respective side edges. A handle assembly consists of a pair of substantially identical handle halves each formed by two longitudinally spaced ends fixed to one of the side folds to a respective side of the crease thereof and a middle section extending between the respective ends and formed unitarily therewith of plastic film. The middle sections are transversely spaced and form an open longitudinally extending gap at least 2 mm wide and aligned with the respective crease. The middle sections extend transversely over less than 80% of a transverse width of the one side fold and have outer edges space at least 5 mm from the respective side edges.

A stand-up bag for pourable goods includes a front wall, a back wall coupled to the front wall at a first side edge and an opposite second side edge, and a base fold, wherein the front wall, the back wall, and the base fold are manufactured from a film, and wherein the base fold provides a standing base and is coupled to lower edges of the front wall and the back wall. The bag further includes a bag top situated opposite from the base fold, a closure device, wherein the closure device is attached proximate the bag top, and a carrying handle on the first side edge between the base fold and the bag top, the carrying handle positioned a distance from the base fold and the bag top.

A bag construction is disclosed of the type having handles and a patch for reinforcing the attachment between the handles and the walls of the bag. The exemplary reinforcement patch includes a fold-over to define a folded top edge of the patch. During construction, a patch having the folded top end is placed in registry with the two ends of the handle that are attached to the wall of the paper bag such that the top edge is generally perpendicular to the ends of the handle. The patch is then affixed over the handle and exterior surface of the bag using glue or other such permanent adhesives. According to a salient aspect, the reinforcing patches are configured to resist tearing, particularly when shear forces are applied that normally act to detach the handles away from the side of the bag.

A method for manufacturing a disposable biodegradable bag for carrying items then discarding the bag without creating unwanted pollution includes providing a first rectangular sheet of biodegradable material having a first top edge, a first bottom edge, and a first pair of lateral side edges. The first rectangular sheet of biodegradable material may be a first biodegradable dryer sheet. The method further includes providing a second rectangular sheet of biodegradable material having a second top edge, a second bottom edge, and a second pair of lateral side edges. The second rectangular sheet of biodegradable material may be a second biodegradable dryer sheet. The method further includes coupling the first bottom edge to the second bottom edge and coupling the first pair of lateral side edges to the second pair of lateral side edges to form a bag having an opening between the first top edge and the second top edge.

A method for producing a tool including a sheet, the method including the steps of: providing a first cellulose sheet; attaching first and second plastic layers each to one side of the first cellulose sheet; upon the attaching, placing a first side of a plastic object on the first plastic layer; pressing a metal object on a portion of a second side of the plastic object; vibrating the metal object parallel to the first plastic layer together with the pressing thereon; and ceasing the vibrating, thereby ceasing the heating.

A flap spreading device that folds back a front flap of a bottom portion of a flat tubular body, conveyed by a bottom folding drum, upside down with respect to a back flap and planarly spreads the front flap and the back flap along an outer peripheral surface of the bottom folding drum in a square bottom forming device of a bag making machine, and includes: a pair of guide plates that guides both side portions of the flat tubular body along a conveyance direction of the bottom folding drum to planarly spread the front flap and the back flap; a pair of robots having the pair of guide plates as end effectors; and a position and posture adjustment device that adjusts positions and postures of the pair of guide plates in a three-dimensional space to target positions and target postures through operations of the pair of robots.
