A punch (2) and a pad (5) are opposed to each other such that a molded portion (3a) of a metal laminate film (3) to be processed is interposed between the punch (2) and the pad (5). An enclosed space (6, 7) is compressed to raise only the temperature of the molded portion (3a) while keeping the vicinity of the molded portion (3a) at a low temperature (S1, S2). After that, the enclosed space (6, 7) is moved with respect to the molded portion (3a) to perform first molding (S3) on the molded portion (3a), and then gas in the enclosed space (6) is released to perform second molding (S4) on the molded portion (3a) by means of the punch (2) and the pad (5).

A construction element can comprise a top portion, comprising a top portion region and a top portion groove located below the top portion region. The top portion groove can be configured to receive a wall material within the top portion groove. The construction element can also comprise a middle portion coupled to the top portion. The construction element can further comprise a bottom portion coupled to the middle portion and comprising a bottom portion groove configured to receive a floor material within the bottom portion groove, a bottom portion bend coupled to and located below the bottom portion groove, and a bottom portion region coupled to the bottom portion bend. Other embodiments are also provided.

A method for producing a seam on a workpiece made of flat material using a bending machine is disclosed. The bending machine comprises a first clamping jaw, a second clamping jaw that is mounted movably relative to the first clamping jaw and configured to clamp, together with the first clamping jaw, the workpiece in a clamping plane, and a bending unit that is arranged on one of the clamping jaws and has a bending tool, the bending unit being configured to bend a portion of the workpiece by moving the bending tool relative to the associated clamping jaw to form a fold. The method comprises producing a pre-seam on the workpiece such that it is located in an area in front of the clamping jaws, comprising forming a fold, wherein the pre-seam extends at an angle relative to the clamping plane, and changing the angle by displacing the bending tool.

A method for forming a sill pan is provided that includes the measurement of a width and length of an opening sill to be sealed. A piece of flexible sill pan material is cut based on the measured opening sill. Fold lines and cuts are created in the piece to form the sill pan. The resulting sill pan is readily formed to have at least one attribute of self-adherence, draining without shims, nail hole self-sealing, and provision of dams without resort to frame cutting.
