摘要:
A tube (1) of fabric reinforced PVC for suspension from a ceiling of a tunnel or the like comprises a tube shaped fabric with an internal and an external coating of PVC. The internal coating is of electrically conducting PVC and the external coating is of electrically isolating PVC. The tube (1) is provided with an external, longitudinal strip (2) of electrically conducting PVC in contact with the internal coating. The strip (2) is earthed by a suspension arrangement (3-5) for the tube (1) to the ceiling.
摘要:
A device for connecting two twin tubes (1, 2) of a cloth material is constituted by
a metal bow (3) in the shape of a "figure eight" arranged in a cloth pocket at the end of a first tube (1), a distance rod (4) arranged in a cloth pocket at the end of a separation wall (1C) between the two tube parts (1A, 1B), a clamp strap (5), which has a shape corresponding to that of the metal bow (3) and is to be arranged over the metal bow in its pocket of the first tube (1) and over the end of the second tube (2) pulled over the end of the first tube, and means (10, 15, 16, 18) associated with the distance rod (4) for tightening the clamp strap (5) to the metal bow (3).
摘要:
A tube arrangement (1) comprises two tubes (2, 3) and a common separation wall (4) between these tubes and is formed of elongated cloths of a heat-sealable material. Each flap (2A', 3A', 4A'; 2B", 3B', 4B') provided at each longitudinal edge of the three elongated cloths - for the two tubes (2, 3) and the separation wall (4) - is heat sealed to an edge portion (2A, 3A, 4A; 2B, 3B, 4B) of another cloth for forming two cloth layers in each part of the joint.

摘要:
A tarpaulin cleaning machine comprises over the machine a rotatable roller (A, B, C) for transferring a tarpaulin (1) from one side of the machine, into the machine for cleaning, and out thereof to the other side of the machine. The machine has a roller set comprising at least two rollers (A, B), each of which is rotatably mounted on an arm (3), pivotable - together with the arms for the other rollers - around a common shaft (2).
