Systems, devices, and methods for extendable conveyors

A conveying system comprising:

• an extendable conveyor, operable to convey items from an upstream side of the extendable conveyor to a downstream side of the extendable conveyor, and configured to increase the distance from the upstream side to the downstream side, and
• a separation module, operable for conveying items towards the extendable conveyor and configured to decelerate the conveying of the items on the separation module wherein the separation module is configured to be positioned relative to the extendable conveyor with a level difference between a conveying surface of the separation module and a conveying surface of the extendable conveyor at its upstream side wherein by decreasing the conveying speed, a deceleration of the items is achieved, and an impulse is imparted on the items, such that a pile of items is separated into single pieces, wherein the item which is the top- and front-most item of the pile falls onto the extendable conveyor,
• wherein the conveying system further comprises a flexible strip curtain, the flexible strip curtain having at least three members, wherein a second member is positioned between first and third members and has a higher flexibility than the first and third members.
