Advantageously, the pipe is formed at site to provide for efficient formation of a pipeline. A transported ISO container providing the material and curable liquid to the site can produce 800 metres of pipeline section, compared with 60 metres in the prior art, representing a significant increase in efficiency.

Thermoforming apparatus (1) for thermoforming an article (2), preferably a permeable article (2′), comprising: an elastic membrane (3,3′); a mould (4,4′); a hot air source (5) configured to blow a hot airflow (6) towards a zone (7) of the apparatus (1) configured to receive the article (2,2′) to be thermoformed; an actuation system (8) configured to move the mould (4,4′) towards the membrane (3,3′) or vice versa to compress the heated article (2,2′) between the membrane (3,3′) and the mould (4) such that an elastic force of the membrane (3,3′) on the article (2,2′) forces the article (2,2′) to assume the shape of the mould (4).2. Thermoforming apparatus (1) according to claim 1, wherein the mould (4′) and/or membrane (3′) are perforated so to permit a transit of the hot airflow (6) from the hot air source (5) to said zone (7). Thermoforming process of an article (2,2′) in a thermoforming apparatus (1) comprising an elastic membrane (3,3′), a mould (4,4′) and a hot air source (5), comprising the steps of: heating the article (2,2′) through a hot airflow (6) blew by the hot air source (5); compressing the heated article (2,2′) between the membrane (3,3′) and/or the mould (4,4′) by uniquely moving the mould (4,4′) and the membrane (3,3′) one toward the other such that an elastic force of the membrane (3,3′) forces the article (2,2′) to assume the shape of the mould (4,4′).

The present disclosure relates to a film for bonding including an embossed surface, wherein the embossed surface has a Sku value of 5 or less, wherein the embossed surface has Sk, Spk, and Svk values, and when a total sum of the Sk value, the Spk value, and the Svk value is 100%, a sum of the Sk value and the Spk value is 50% or more, wherein the embossed surface has a Sz value of 30 to 90 μm, and wherein the film includes a polyvinyl acetal resin and a plasticizer.

A compression molding system includes a first extruder to output melted plastic, and a second extruder downstream from the first extruder to mix the melted plastic with wood chips to output a composite material. A transfer valve alternately directs the composite material between inner block molds and outer block molds. Each inner block mold has an inner block press associated therewith to press the composite material into a desired shape of an inner block having an opening on one side. Each outer block mold has an outer block press associated therewith to press the composite material into a desired shape of an outer block having an opening on one side. A press assembly presses one of the inner blocks into the opening in one of the outer blocks to form a double wall block.
