Abstract:
An apparatus is disclosed for flipping over flexible and limp planar workpieces such as fabric. The apparatus includes a primary workpiece propeller having a cylindrical means for contacting the workpiece about a central rotating axis. A slot of sufficient size to receive the workpiece is positioned in a vertical orientation beneath the primary propeller. The slot preferably has a flared upper end positioned directly beneath and in contact or near contact with the propeller. The fabric is drawn into the slot by the rotation of the propeller and follows the contour of the flared open end of the slot. The fabric enters into the slot until the trailing edge of the fabric is in contact with the primary propeller. The trailing edge of the fabric is gripped by the propeller and thereby drawn to the opposite side of the flared opening of the slot and is subsequently pulled out of the slot. The fabric has thereby been inverted so that the top of the fabric is now on the bottom.
Abstract:
A device for slowing cut sheets in seriatum flow by nipping the trailing edge of the sheets as they leave a high-speed conveyor system is provided whereby the sheets pass to a stacking pile at a slow speed. The nipping device is provided in several embodiments including a brush carrying roll, an oscillating roll on a lever arm and an air jet. Ream removal apparatus are also provided to remove reams of paper from the bottom of the stacking pile.
Abstract:
Sheet-like products coming off a folder are firstly transported some distance before being caused to overlap. In order to slow down the products to cause this to take place and to arrange them in a perfectly regular feed stream without being damaged, the products are engaged by grippers that are moved along a preferably arcuate path on a support in the course of which the products are slowed down by the grippers to the speed of a delivery belt on which the products are then deposited.
Abstract:
A sheet piler for sheets transported end-to-end at high velocity, has a reciprocating suction bar for reducing the sheets' traveling velocity so that their forward travel can be stopped without damaging the sheets, with the stopped sheets forming a pile. Rotating brushes press the sheets' trailing ends momentarily against the suction bar and the latter then reduces the sheets' travel velocity.
Abstract:
A sheet discharging device includes a stacking portion configured to stack a sheet; a discharging portion configured to feed the sheet so as to be discharged to the stacking portion, wherein the discharging portion includes a first roller configured to feed the sheet and a second roller provided so as to be contactable to a sheet surface opposite from another sheet surface to which the first roller is contactable to; and an electrically discharging member configured to electrically discharge the sheet in contact with the sheet fed by the discharging portion. As viewed in a widthwise direction perpendicular to a discharging direction of the sheet, the electrically discharging member is provided so as to extend through between rotational axes of the first and second rollers in the discharging direction of the sheet.
Abstract:
A reversing device for a film web, which has a take-off device, has at least one turning device and at least one deflecting roller. The film web can be guided by the take-off device via the at least one turning device and the at least one deflecting roller to a winding device. The axes of the take-off device, the at least one turning device, and the at least one deflecting roller are adjustable in angle relative to one another. The at least one deflecting roller is formed as an expander roller having an expanding capacity which increases towards the end faces of the deflecting roller.
Abstract:
A print media discharge unit includes a print media transport path along which in operation a sheet of print media is transported in a transport direction. The print media transport path is defined by a first electrically isolating print media guide and a second electrically isolating print media guide. The print media discharge unit further includes an electrically grounded electrically conductive discharge element extending through an opening in at least one of the first and second electrically isolating print media guides into the print media transport path. At least one of the first and second electrically isolating print media guide includes a plurality of guidance ribs aligned substantially in the transport direction at an angle with respect to the transport direction.
Abstract:
A sheet discharge device includes a sheet discharge portion configured to discharge a sheet, a destaticizing brush coming into contact with the sheet discharged by the sheet discharge portion and destaticizing the sheet, and a guide member turning by being pushed by the sheet discharged by the sheet discharge portion and guiding the sheet to a stacking portion on which the discharged sheet is to be stacked. The guide member includes a guide portion guiding the discharged sheet to the stacking portion and a recede portion provided at a position facing the destaticizing brush and accepting the destaticizing brush deformed by being pushed by the sheet.
Abstract:
A paper feeding apparatus includes a bracket. A first feeding shaft is pivotably mounted on the bracket. A number of first feeding rollers is mounted on the first feeding shaft. The first feeding rollers rotate together with the first feeding shaft to contact a sheet of paper and move the paper forwards. A number of fans are mounted on the first feeding shaft. The fans rotate together with the first feeding shaft to drive air against the paper to prevent it becoming wrapped around one of the rollers.
