Abstract: A pair of regulating guides is disposed on both sides of a conveying belt in a sheet width direction Y, each having a support surface that supports an end edge in the width direction of the sheet conveyed while being nipped by the conveying belt and balls and a guide surface that faces the end edge of the sheet in the width direction. Each of the pair of regulating guides is movable to a first guide position at which the end edge of the sheet in the width direction is supported by the support surface and guided by the guide surface and to a second guide position at which the end edge of the sheet in the sheet width direction is supported by the support surface and which is retracting further away from the end edge in the sheet width direction than the guide position.

Abstract: A method for stimulating or enhancing the immune system with a composition that includes a Eurycoma longifolia aqueous extract. Also provided is a method for reducing the risk of infectious disease by administering the composition. Further disclosed is a method for treating an individual with a Eurycoma longifolia aqueous extract to increase the number of T-cells, improve Scoring of Immunological Vigor, lower immunological age, reduce fatigue, or alleviate or reduce stress.

Abstract: The present invention discloses the use of a composition comprising an effective amount of an extract of Eurycoma longifolia for the production of a preparation to stimulate and/or enhance the immune system. In a preferred embodiment, the extract comprises active ingredients, which include eurycomanone, protein, polysaccharide and glycosaponin in appropriate amounts. In another preferred embodiment, the extract has an activity selected from the group consisting of: increasing the number of T-cells; improving Scoring of Immunological Vigor (SIV), a comprehensive index of overall immune function; lowering the immunological age, a comprehensible form of immune function based on T-cell number and proliferative activity; reducing fatigue; and alleviating or reducing stress. Also disclosed is a method of for treating an individual to achieve an outcome selected from the group consisting of increasing the number of T-cells, improving SIV (i.e.
