Abstract
Abstract A table for feeding and aligning sheets of paper, cardboard or the like comprising a middle part and two lateral parts, the lateral parts being movable toward or away from the middle part. All three table parts are provided with upper and lower guides for a sheet. The lateral parts are adjustable independently from one another relative to the stationary middle part of the table for accommodating non-symmetric sheets. The adjustable table parts comprise spring bands arranged on edge and interconnected at spaced points with one another, with the middle table part and with lateral guides. Means for adjusting the drive of an inclined conveyor belt to the various positions of one of the lateral guides.

Total Claims: 7
Claim 1
Independent Claim
167 words
In an aligning table for sheets of paper and the like having along one of its sides a guide member for one of the side margins of the sheet, a conveyor belt inclined to and adjoining said guide member and said guide member having hold-down means for holding said one margin of the sheet onto said belt, characterized in a stationary middle member forming a central supporting member of said table for supporting a midregion of a sheet, two lateral members for supporting opposite side margins of such sheet, a first one of said lateral members being defined by said first-mentioned guide member and said conveyor belt, means for moving said lateral members respectively away from and toward said middle member so as to accommodate different sheet widths, and hold-down rails arranged, respectively above and associated with said central supporting member and with said other lateral member, said hold down rails and said hold down means holding down a mid-portion and both marginal portions of a sheet.
Claim 2
Dependent Claim
