Abstract:
Method for transporting pellets of a glass fibre reinforced thermoplastic polymer composition from a loading position to an unloading position, said pellets comprising a core and a thermoplastic polymer sheath surrounding said core, wherein the core comprises glass fibres extending in a longitudinal direction of the pellets and an impregnating agent, the method comprising loading pellets onto a non-vibrating belt conveyor at said loading position, conveying the pellets by means of said non-vibrating belt convey—or to said unloading position and unloading the pellets from said non-vibrating belt conveyor at said unloading position. Further methods are claimed as regards a process for manufacturing pellets of a glass fibre reinforced thermoplastic polymer composition and a process for the manufacture at a moulding position of a moulded product from pellets of a glass fibre reinforced thermoplastic polymer composition.
Abstract:
A conveyor belt comprising at least one belt edge (1) arranged on a longitudinal side of the conveyor belt (10) is characterised in that threads of a tear-proof material (6) are arranged in the belt edge (1). The threads are preferably embodied as fabric and arranged as a fabric inlay (6) in the belt edge. A higher strength is thereby achieved.
Abstract:
A connection line for a belt portion held between a driving roller (41) and a pinch roller (42a) and for a region extending from the vicinity of the belt portion to the outer peripheral edge is a single straight line or a gentle curve having a large angle with respect to a tangent to the peripheral line of a belt. The connection for the outer belt portion is by means of a finger joint. Further, the connection for the belt portion held between the driving roller (41) and the pinch roller (42a) and for the region extending from the belt portion to the outer peripheral edge is by means of a finger joint using fingers installed with a large pitch, and the connection for the other belt portion is by means of a finger joint using fingers installed with a small pitch. Thus, it is possible to provide a curve conveyor belt with no peeling or break occurring in the joint portion for a long time, the thickness of the joint portion not becoming large, and at low cost.
Abstract:
A strip of plastics material (14) for forming a wall of a conveyor belt is subjected to a continuous preliminary shaping operation which imparts a corrugated profile to the strip. Successive portions of the pre-shaped continuous strip (14) are subsequently welded onto the surface of the belt by means of separate welding steps.
Abstract:
The invention relates to a belt conveyor for transporting goods, consisting of at least one conveyor belt (3) and two rollers (1,2). In order to stabilise the movement of the conveyor belt (3) in a direction perpendicular to the transport direction and possibly also in the transport direction, a bottom side of the conveyor belt (3) is provided with a row of projections (4) and the rollers are each provided with a groove (5,6) via which the row of projections (4) may pass.
