Abstract

938,500. Feeding sheets. DERITEND ENGINEERING CO. Ltd. Aug.. 30, 1962 [Sept. 23, 1961], No. 34142/61. Class 100 (1). In apparatus wherein cardboard blanks g are separated sequentially from the bottom of a stack by means of an endless belt a, a<SP>1</SP> which is perforated or slotted and associated with a vacuum chamber e<SP>1</SP>, the blanks being moved between a pair of constantly rotating feed rollers i which effect the removal of the blanks, the belt is driven intermittently and is stationary when the rollers i commence their feeding action. As shown, the belt a, a<SP>1</SP> passes over a forward roller c and is situated on the top of a chamber e<SP>1</SP> which communicates with a chamber f housing an extraction fan, so that the bottom blank g<SP>1</SP> is held flat on the upper run a of the belt by suction. The chamber e<SP>1</SP> can be portioned and sections can be shut off when small blanks g are used. The roller c has a gear c<SP>1</SP> in mesh with a gear h<SP>3</SP> driven through a pawl-andratchet or other one-way clutch by a lever h<SP>2</SP>. The lever h<SP>2</SP> is oscillated by a connecting-rod h<SP>1</SP> on a crank secured to a rotating member h of a printing, slotting, or other machine, and provision is made for the correct timing of the feeding of a blank to the machine, e.g. by adjusting the setting of the rod h<SP>1</SP> on the member h. The bottom blank is fed through a gap d<SP>1</SP> below a front stop d, and to assist this operation an auxiliary vacuum chamber j, which communicates with a centrifugal fan in a chamber j<SP>1</SP>, is arranged to pull down the leading edge of the bottom blank. An automatic brake k to arrest and prevent over-run of the belt a, a<SP>1</SP> is provided. Where the auxiliary chamber j is not provided, the forward belt roller c is arranged beneath the stop d. The perforated or slotted wide belt may be replaced by a number of spaced narrow parallel belts.
