Title: Closure of wide, heavy fabric seams - using pintle through intermeshed arrays of attached loops
Inventor: MACBEAN DONALD GEORGE
IPC: D21F1/00
Filed: 1976-05-25
Abstract: An improvement is claimed for the joining the seams of a wide heavy fabric having respective ends to be pupped together and their edges joined to form an endless band, the edge of each of the ends being provided with a lateral array of spaced loops adapted to be intermeshed with the other similar array to form an elongated tubular passage for receiving a pintle to complete a hinge-type joint.

Title: Articulated spreader draw roll - for transverse drawing of a travelling strip, has individual rolls of cardan bearing type construction
Inventor: STOEBI JOHANN
IPC: B65H23/025
Filed: 1976-08-28
Abstract: An articulated spreader draw roll for travelling strips, e.g. of paper or textile material, has a straight shaft (A) on which adjacent rolls are mounted and driven thereby. The rolls are adjustable w.r.t. shaft (A) in different surfaces of revolution. Pressure rolls acting eccentrically on the side of the two outermost rolls cause the rolls to take up an inclined position with respect to the shaft (A) of magnitude dependent on their position and decreasing towards the centre of the roll assembly. The rolls are pushed onto the shaft (A) on both sides of a fixed centrepiece on (A). Each roll is tiltably fixed to (A) by a shaft pin which is a press fit in a diametral bore in (A). Each roll consists of an inner supported on the ends of the shaft pin projecting from (A), and an outer ring fixed to the inner ring so as to be tiltable around rods perpendicular to the shaft pin. This outer surface of this outer ring forms the roll surface. The ring is provided with surfaces at positions situated at some distance within its periphery for lying against the adjoining roll or the fixed centrepiece, with an interposed slider ring. The arrangement avoids the tendency for rapid wear to occur and prevents jamming of the strip material between the rolls or the marking of the material e.g. by worn and sharp edges.
