The bottom sheet (6) comprises one or more respective sets of bottom sheet flaps (50). At least one bottom sheet flap (50) comprises a bottom sheet flap proximal portion (50P) hingedly attached to the bottom sheet (6) about a respective bottom sheet flap proximal hinge line (52) defined at the respective bottom sheet opening (12) and a bottom sheet flap distal panel (50D) hingedly attached to the bottom sheet flap proximal panel (50P) about a respective bottom sheet flap distal fold line (62). The bottom sheet flap (50) is folded about the respective bottom flap proximal hinge line (58) such that the bottom sheet flap proximal panel (50P) defines at least in part a pocket side wall (74), and the bottom sheet flap distal panel (50D) defines at least in part a base wall (64) of the pocket (8). Within each pocket (8), at least one top sheet flap distal panel (28D, 30D, 32D) is adhesively secured to the bottom sheet flap distal panel (50D).

A method for manufacturing flexible paper straws and flexible paper straws are revealed. The method includes the steps of preparing a paper tube which is a spiral tube by glue and paper, inserting a support shaft into the paper tube axially, placing the paper tube with the support shaft between a first roller and a second roller before curing of the glue while the first and second rollers are in parallel and having a plurality of circular grooves on a cylindrical surface thereof, rolling the paper tube by the first and second rollers to form a corrugated portion on a part of the paper tube, squeezing the corrugated portion to compress the corrugated portion for a period of time for curing the glue and holding shape of the corrugated portion, and removing the support shaft to get a flexible paper straw which is bendable at the corrugated portion.

A pre-punched material sheet for constructing a packaging trough, the material sheet includes a sub-area that has been punched out incompletely so that the sub-area is connected to a residual area of the material sheet through a plurality of retaining lugs. The material sheet is positioned on top of a female die part of a forming tool and the sub-area at least partially covers an opening of a forming cavity of the female die part. The residual area of the material sheet may be clamped in position against the female die part. The sub-area of the material sheet is sucked onto an insert in the forming cavity using a vacuum. The insert is vertically movable in the forming cavity from a first position to a second position to draw the sheet into the forming cavity and thereby form the packaging trough.

The invention relates to a heating module and a primary reflector for a heating module of a heating duct of a molding machine for producing containers from preforms, in which preforms made of thermoplastic are heated, which is provided between tubular heating units arranged in parallel and one over another on a side wall of the heating module and the side wall and consists of ceramic material, and is characterized in that the primary reflector is connected via a dovetail connection to the side wall, wherein a connecting region in the form of a dovetail is formed in each case on the reflector, which is fixable in each case with a clip made of steel, in particular spring steel, fastened on the side wall, having dimensions adapted to the dovetail.
