用于自动，连续生产预成型件的设备和工艺

Apparatus and process for automatic, continuous production of preforms
Abstract:
An apparatus and a process for automatic, continuous production of preforms from dry fabrics containing a thermoplastic binder element by feeding individual layers (7-9) of dry fabrics towards an ultrasonic unit (13), applying ultrasonic energy from said ultrasonic unit (13) to said more than one layers (7-9) of dry fabrics applying pressure to said more than one layers (7-9) of dry fabrics containing a thermoplastic binder element while the binder element is activated by means of said ultrasonic energy in said ultrasonic unit (13), to create a consolidated, stiff laminate (18) and cutting said consolidated, stiff laminate (18) to a preform.
Abstract(Chinese):

一种用于通过将干织物的各个层（7-9）送往超声波单元（13），从所述超声波单元（13）施加超声波能量，从含有热塑性粘合剂元件的干织物自动连续生产预成型件的装置和方法， 到所述多于一层（7-9）的干织物，其在包含热塑性粘合剂元件的所述多于一层（7-9）的干织物上施加压力，同时通过所述超声波中的所述超声能量来活化粘合剂元件 单元（13），以形成固结的刚性层压板（18），并将所述固结的刚性层压板（18）切割成预制件。
