Abstract: A container-lifting device includes a cam, and lifting elements. Each lifting elements has a container carrier on a slide element, a deformable fluid-pressure actuation element, and a guideway, separate from the actuation element, for guiding the slide element. The lifting element moves between first and second lifting positions. The control cam interacts with the slide elements to move them into the second lifting position. The actuation element, when pressurized, pretensions the slide element into the first lifting position. The actuation element has a wall that delimits an interior chamber to which the fluid pressure is applied. The actuation element is a ball-type element, a membrane-type element, or a bellows-type element.

Abstract: An apparatus for feeding a fiber lap to a card, includes an upper reserve chute having an upper end through which fiber material is introduced into the apparatus, a feed roller situated at a lower end of the reserve chute and arranged for withdrawing fiber material therefrom; a feed chute having an upper end situated adjacent to the lower end of the reserve chute; and an opening roller situated in a space between the lower end of the reserve chute and the upper end of the feed chute. The opening roller is arranged under the feed roller to receive fiber material therefrom and to advance the fiber material into the feed chute through the upper end thereof.
