Title: Mfr. of profiles, e.g. extruded thermoplastics sections - using two closely adjacent belt haul=off(s) for increased prodn. avoiding speed or space increase
Inventor: TOPF SIEGFRIED
IPC: B29C48/12
Filed: 1991-06-01
Abstract: Two profiles are extruded simultaneously through adjacent dies and run through parallel calibrating/cooling and haul-off units (16,17). The haul-offs consist of pairs of superimposed driven endless belts (10 to 13). The upper belts are mounted on inverted 'L' supports (14,15) close to each other. The haul-offs (16,17) pref. form a single unit. The vertical gap between the belts is pref. adjusted by moving support beams (14,15), e.g. by electric motors. The motors may be controlled by force transducers sensing the contact force on the extruded profile. One or both belts of each pair may be tiltable, up to 15 deg., on a longitudinal pivot, to accommodate profiles with non-parallel or non-planar surfaces, without damage to the profile or increased wear on the belts. For substantially non-parallel surfaced profiles, the belt pivot may be offset from the belt centre to allow for the lateral movement of the belt when tilted. USE/ADVANTAGE - Extruded thermoplastic profiles, e.g. window frame sections. Increased productivity with negligible increase in space required and without increase of calibrating speed.

Patent DE-4204550-A1 (DE)
Inventor: ANDJELIC MILAN DR
IPC: B65H26/04
Filed: 1992-02-15
Abstract: When the means producing the normal tension in a running web suddenly stops, a device immediately responds to the stoppage to apply a tension to the web approximating to the normal tension. Tension in a web 4 being pulled from roll 3 by driven rollers 5 of web processing apparatus 6 is normally regulated by dancer rollers 9 on carriage 14 which, through linkages 16-31, adjusts the braking force on the roll 3. Should apparatus 6 fail or rollers 5 be abruptly stopped, eg by operation of switch 47, carriage 14 might not fall quickly enough to keep up with the growing web loops 11. Under these circumstances, device 32 including a pneumatic motor drives the carriage 14 downwardly so that rollers 9 remain in contact with the bights of loops 11. <IMAGE>

Patent DE-4231506-A1 (DE)
Inventor: REMER LUCIUS
IPC: G02B21/36
Filed: 1992-09-21
Abstract: In this method, a restrictor plate (4) comprising several discrete restrictors (2, 3) disposed in the measurement-beam path (M) and a masking plate (11) comprising several discrete masks (12, 13) disposed in the imaging-beam path (E) in the vicinity of a graticule (7) are moved synchronously so that the restrictor (2 or 3) positioned in the measurement-beam path (M) is simultaneously imaged in the ocular intermediate-image plane (19) in the viewing-beam path (B) via the imaging-beam path (E) by means of the associated mask (12 or 13) and the graticule (7) which has the same outline as the restrictors (2, 3). The device is designed in such a way that the graticule (7) contains the inverse outline, or inverse-outline fragments, of the restrictors (2, 3) on the restrictor plate (4), e.g. in the form of lines, dotted lines, dots or crosses. These outlines are present on the opaque graticule (7) as transparent recesses so that the viewer sees the images of the corresponding outlines brightly lit in the ocular intermediate-image plane (19). Instead of a restrictor plate (4) or masking plate (11), the device may have a pair of restrictor plates (20, 21) or an analogous pair of masking plates. This makes it possible for the restrictor or masking plate to have a large number of different shapes.
