Abrégé

The invention relates to a method for processing plastic waste from a polymeric base material, in which method an adjustable amount of at least one additive is added to the melt processed by a melt treatment apparatus (7). The melt is mixed with the additive in a mixing apparatus (15) downstream of the melt treatment apparatus (7) and a common melt–additive mixed stream is output from said mixing apparatus. Subsequently, a first value of at least one parameter of the added additive is determined as the first actual measured value and is forwarded to an open-loop and closed-loop control device (4). The actual measured value is subtracted from a target value of the parameter stored in the open-loop and closed-loop control device (4) and a differential value is formed. The added amount of the at least one additive is increased or reduced or remains unchanged on the basis of the determined differential value.

Abrégé

In a method and an apparatus for increasing the intrinsic viscosity of a polycondensate melt at negative pressure, the melt enters a chamber, in which a negative pressure of less than 20 mbar prevails, through a perforated plate or a screen having openings with a diameter of less than 0.5 mm. The melt passes through this chamber in free fall in thin threads and remains in a reservoir beneath the chamber for at least one minute. The melt is moved constantly in the reservoir, and discharged from the reservoir, by a helical mixing and discharge part.

In a method and an apparatus for increasing the intrinsic viscosity of a polycondensate melt at negative pressure, the melt enters a chamber (25), in which a negative pressure of less than 20 mbar prevails, through a perforated plate or a screen (16) having a plurality of openings (26) with a diameter of less than 0.5 mm. The melt passes through this chamber (25) in free fall in thin threads and remains in a reservoir (19) beneath the chamber (25) for at least one minute. The melt is moved constantly in the reservoir (19), and discharged from the reservoir (19), by a helical mixing and discharge part (27).

Abrégé

A device for removing impurities from a polymer melt has a chamber (25) which is under negative pressure and has at least one opening (26), through which the polymer melt enters the chamber (25). The polymer melt falls down through the chamber (25) in the form of thin filaments of melt and impurities such as water diffuse to the surface and evaporate as a result of the temperature and the negative pressure.

Abrégé

The invention relates to a device for stretching film sections in a monoaxial or biaxial manner, preferably by way of a tenter frame, for films made substantially of polymers, wherein a square or rectangular section of a such film is seized at 4 sides by at least two tenter hooks each, designed as regards improved stretching such that the upper tenter hook part (11) is mounted in an articulated fashion on a rotational axis located outside the film to be stretched, and specifically such that the lower, fixed tenter hook part (13) carries the joint, while the upper tenter hook part (11) is designed so as to pivot upwards and at least one cylinder (14) is disposed rotated by 90° for applying the tensioning power and thus applies the tensioning power to the upper pivotable tenter hook part (11).
