Transfer, Smoothing, and Stretching
| Transfer position of the clamp onto the vacuum transfer bar - Following spreading, the vacuum transfer bar moves against the item, the clamps lower to the vacuum transfer bar, open, and the item's leading edges full surface is placed on the vacuum transfer bar. |
 |
| Transfer with the speed regulated transfer profile. The leading edge of the item is transferred in its natural attitude. - The vacuum transfer bar moves forward taking the leading edge of the item with it. Without altering its natural attitude, the item is transferred onto the transport belts, the speed of which is synchronized with that of the vacuum transfer bar. The efficient vacuum acting beneath the perforated transport belts ensures that all items are safely held in place, from the lightweight polyester cotton sheet to the heavy cotton duvet cover. |
 |
| The interaction of vacuum transfer bar and Duo vacuum ensures a square and straight leading edge of the item - As soon as the leading edge of the item is spread and lies on the vacuum transport belts, the in-feed roller transports the item into the vacuum chute, which is designed to fully shake-out even the very long pieces. The strong, uniformly distributed air flow causes an intensive shake-out action. During their transfer into the transport system of the feeding machine, the items are pulled over smoothing brushes running in opposite directions. |

Special Program for Table Linen
Following the sensitive, automatic spreading the vacuum transfer bar lays the item onto the perforated transport belts with Duo vacuum. Subsequently, the item enters the wedge shaped in-feed zone of the stretching conveyor and triggers a photocell for a brief intermediate stop. As the conveyors have two seperate drives, the stop function allows the leading edge to be stretched and smoothed which is very beneficial for the selvedge.
If required, upper brushes can be added to smooth out the side edges of the item. If tablecloths (e.g. round cloths) are to be fed manually, the feeding belts will stop automatically by program once an item has been laid on them. Consequently, the tablecloth can be placed on the resting transport belts and be adjusted manually. The belt restarts moving as soon as the hand is removed from the photocell beam.
