Abstract: An erectable horizontal work surface apparatus having a work surface pivotally connected to two sets of legs and removably connected to brace members for the sets of legs. The brace members are removably connected to the legs. When in the assembled position, the legs are extended at an angle somewhat perpendicular to the work surface and one end of the brace members are placed in brace member reception notches so as to connect the brace members to the legs. The opposite end of the brace members are connected to the work surface by use of a removable dowel member. To place the apparatus in a disassembled position, such as for transporting or storage, the dowel member is removed from its reception notch thus allowing the brace members to fall free. The legs are then pivoted toward the work surface until they are placed in a position that is parallel or horizontal with the work surface.

Abstract: Header cards adapted for folding around small flexible articles, such as infants vinyl pants, are packaged on an automatic folding machine. The folding machine includes a first station for automatically feeding unfolded header cards from a magazine onto a conveyor. A second station provides for folding of a first flap onto the header card using an inclined bar and a plunger assembly. A third station provides for folding and sealing the two side flaps, while the fourth station holds the package together until the adhesive has had a chance to set.

Abstract: Apparatus for positioning a number of nondestructive dud detectors above a conveyor includes side support members to which a rotatable threaded positioning bar is mounted. The positioning bar includes a number of serially placed threaded positioning segments. The dud detectors are supported by the positioning bar through individual dud detector supports. Each dud detector support includes a threaded block which engages the threaded positioning bar. The threaded positioning segments have threads with different pitches. Rotation of the positioning bar cause the dud detectors to move axially along the positioning bar, and thus transversely over the conveyor belt, at unequal rates. The thread spacing or pitch for each threaded positioning segment is chosen so that the separation between adjacent dud detectors changes while keeping the dud detectors equally spaced.
