Conveyer belt and apparatus

摘要

A conveyor belt comprising knit fabric of high practicality, and an apparatus which uses such a conveyor belt. The conveyor belt includes weft knit fabric. Suction of air from below belt(s) is used to convey sheet-like and/or small thing(s) which are object(s) to be conveyed that are placed. The strength of filament(s) of knit fabric at side end(s) is adequately maintained. Loops exhibit mutual intertwining of filament(s) Pitch Ps of loops in width direction is formed so as to be smaller than pitch Pg of loops in conveying direction. Adjacent loops are mutually flattened and filament(s) of loop(s) are entangled, mutual intertwining of filament(s) causes knit fabric to have suppressed percentage elongation and increased strength in conveying direction, fraying of filament(s) at side end(s) of belt(s) is prevented, and strength is adequately increased.

主权项

1. A conveyor belt having knit fabric suited for conveying paper, sheets or objects by virtue of air permeability by suction of air, comprising:
weft knit fabric; yarn, which forms the conveyor belt, includes a filament that is synthetic continuous fiber; the filament of the yarn is mutually intertwined to form a knit pattern having mesh loops such that pitch of the mesh loops formed in a stitch direction which is a width direction is smaller than pitch of the mesh loops formed in a gauge direction which is a conveying direction; a state is maintained in which the mutually contacting mesh loops are deformed and the filament of the mesh loops are entangled so as to increase the strength in the conveying direction as a result of the mutual intertwining of the filament thereby increasing the strength and preventing fraying of yarn filament at belt side ends during conveying by the conveyor belt.
