A feed apparatus for isolating and feeding spirals (3) or the like to a
binding apparatus has an isolating roll (12) comprising depressions (19),
which are distributed over the circumferential surface (11) thereof and
are parallel to the axis, for receiving in each case a spiral (3), which
circumferential surface (11) is moved under a scraper (20) which
comprises a chain (25) which is moved in the opposite direction over two
rollers (21, 22) arranged vertically one on top of the other and which
carries outward-projecting scraping fingers (27) which are in the form of
bundles of resilient bristles. From the circumferential surface (11), the
spirals (3) pass via a baffle plate (40) onto a conveyor (30) having
drivers (37) which transport them to a slot (43), where they are
delivered to the binding apparatus. If no spiral (3) was picked up by the
depression (19) of the isolating roll (12) and further transported to the
conveyor (30), the baffle plate (40) is advanced in the conveying
direction for avoiding a failure.
