A separator separates sheets from a bundle. Slack in the strap used to raise and lower a clamp is used to determine when the clamp reaches the bundle. A non-horizontal conveyor tilts beneath the clamp to receive multiple articles, and then tilts over another bin to deposit the articles. The second bin includes an angled surface, which is straightened to shift the articles for clamping. The clamp is supported by, but not attached to, a support connected with the drive. When the clamp reaches the pile, the clamp stops but the support may continue to move. The clamp is tiltable. The article is transferred by an air jet onto a surface with a roller separated from the surface. Upon transfer, the roller forms a nip with the surface. The article is deposited on an exit conveyor having a flexible, raised portion.
