Title: High-grade fibre-reinforced thermoplastic composite sheet prodn. - by impregnating fibre sheet, esp. silanised glass fibre, with polyamide or polycarbonate etc. for short time under pressure, at specific temps.
Inventor: GOLDMANN GERD DIPL ING DR
IPC: B29C70/46
Filed: 1991-05-23
Abstract: Prodn. of high-grade composites (I) with a thermoplastic matrix, by impregnating sheets of reinforcing fibre (II) with the thermoplastic (III) in a press for a short time under pressure, with a precisely defined max. residence time for individual vol. elements; the novelty is that the process is carried out at a very high temp. which would normally be expected to result in damage to (III) by itself or to the surface coating on (II) or to produce damage due to the degradation of (III) at the matrix/fibre interface under the action of the surface coating. USE/ADVANTAGE - The method provides a new process for the prodn. of high-grade composite sheet with mechanical strength values considerably higher than the corresp. PU resin/GF composite; high-temp. impregnation enables a considerable increase in prodn. (short residence time) without thermal damage

Patent DE-4307505-A1 (DE)
Inventor: GREIVE MAREN
IPC: B65H1/18
Filed: 1993-03-10
Abstract: Before the top sheet 10 is separated from the pile by suckers 2 and delivered to feed rollers 3/4, it is aligned against stop 14 and/or 12 by a rotary member above the pile. The member may be rotatable in only one sense and rotatably driven in this sense to urge sheet 10 against the stop(s), the drive then being discontinued to allow the aligned sheet to rotate the member further as the sheet is pulled from beneath the member. Alternatively, rubber rings 25, rotatable only in a clockwise sense on shaft 24, move from the position shown to the left as arm 15 descends and lever 23 pivots clockwise. The rings do not rotate during this movement, sheet 10 thus being aligned against stop 14. Arm 15 then ascends, lever 23 pivoting anti-clockwise and rings 25 rolling on the aligned sheet. <IMAGE>
