Abstract
This plant for manufacturing fiber-reinforced thermoplastic structural components, especially for motor vehicles, is characterized in that it includes: means (1) of continuous production of a dough of a fiber-reinforced thermoplastic compound, receiving as input, on the one hand, the thermoplastic (4) and, on the other hand, the reinforcing fibers (6); means (14) of accumulation and of temporary storage of the dough produced; and means (26) of removing the dough from the accumulation and temporary-storage means (14) and of introducing this removed dough into a mould (29) for forming the component.

A plant for manufacturing structural components made of fibre-reinforced thermoplastic, characterized in that it comprises:
- means (1) of continuous production of a dough of a fibre-reinforced thermoplastic compound, having input means for receiving the thermoplastic (4) and the reinforcing fibres (6);
- means (14) of accumulation and of temporary storage of the dough produced, comprising a reservoir-forming storage means (15) provided with an inlet connected to the production means (1) and an exit provided with shut-off means (16) connected to means of controlling the opening and closing of these shut-off means;
- and
- means (26) of removing dough from the accumulation and temporary storage means (14) and of introducing this removed dough into a mould (29) for forming the component, these means (26) comprising syringe-formed means (27) which include at least one dough charging/discharging orifice (28), which means are carried by handling means (38) and can move between a first position for charging with dough, in which position the dough charging/discharging orifice (28) of the syringe-formed means (27) is opposite the exit of the dough accumulation and temporary-storage means (14) and the shut-off means (16) of this exit are opened in order to allow transfer of the dough from these accumulation and temporary-storage means (14) to the syringe-formed means (27), and a second position for introducing the dough with which these means are charged into the mould (29) for forming the component.

- and
- means (26) of removing dough from the accumulation and temporary-storage means (14) and of introducing this removed dough into a mould (29) for forming the component;
- in that the dough accumulation and temporary-storage means (14) are formed by temperature-regulated reservoir-forming storage means (15) which are arranged at the exit end of the production means (1), the inlet of which is connected to the exit of these production means and the exit of which includes shut-off means (16) connected to means of controlling the opening and closing of these shut-off means;
- and
- in that the reservoir-forming storage means (15) comprise a first reservoir part (17), a first end of which forms the inlet of these means and is connected to the production means (1) and a second end of which forms the exit of these means, this second end being provided with said shut-off means (16), and a second reservoir part (18) which extends from the first reservoir part (17), dough compaction/ejection means being arranged in this second part (18).
