DEVICE TO PRODUCE FIBROUS WORKPIECE WITH RANDOM GEOMETRY OF SURFACE USING TFP-TECHNOLOGIES Russian patent published in 2010 - IPC B29C33/30 

FIELD: process engineering.

SUBSTANCE: invention relates to device designed to produce fibrous workpiece with whatever preset geometry of surface using TFH-technologies. Technical result is accomplished by the device designed to produce fibrous workpiece with whatever preset geometry of surface using TFH-technologies. Note here that said device places fibrous strand by guide appliance along any preset trajectory on elastic and flexible bearing layer. Device secures said strand on bearing layer by one fixing thread with the help of sewing head. Proposed device arranges bearing layer in "xy"-direction with respect to guide appliance with sewing head. Proposed device arranges bearing layer in "z"-direction with respect to guide appliance with sewing head. Device varies bearing layer surface geometry with the help of multiple plungers arranged under bearing layer to make a matrix and furnished with support means.

EFFECT: device designed to produce fibrous workpiece with whatever preset geometry of surface using TFH-technologies that requires minor modifications in known TFP-techniques.
