Abstract
Abstract An improved belt conveyer comprising a pair of endless belts partly contacting each other so as to form a conveying passage. One conveyer belt has one surface entirely covered with male elements of a velvet type fastener while the other belt has one surface entirely covered with female elements of the fastener. The male elements of the belt engage with the female elements of the other belt at the conveying passage. In this passage, the endless belts are guided by guide rollers in interlocked condition capable of displacing away from each other whenever an article is conveyed by them.
