Abstract: There are disclosed embodiments of a decurler system for tag webs used for example in printers and stackers to automatically remove curl from tag webs to promote further tag handling and better tag appearance. The decurler system may determine the current diameter of a stock roll and gradually adjust parameters such as resistance and back bend so as to compensate for increased set in tag webs as the diameter of the stock roll decreases. In an embodiment, the decurler system may include different sets of parameters for different stock roll diameters depending on the material used for the tag webs.

Abstract: Disclosed are a printer and a stacker and methods. The printer prints selectively on one or both sides of a printable web and sheets or labels are cut from the web and stacked in the stacker. The printer has an unwind mechanism that accepts and holds web rolls of different widths in center-justified relationship with respect to a print head. The printer has a spindle for mounting an ink ribbon core with a detent for center-justifying the ink-ribbon with respect to the print head.

Abstract: There is disclosed a printer including a print head and a mounting assembly for a web roll having a core. The mounting assembly can center-justify the roll with respect to the print head. The roll can be loaded simply by pushing the roll slidably onto the mounting assembly and unloaded by pulling the roll or its core slidably off the mounting assembly using one hand. In some embodiments, there is no need separately to undo any latch or to free the roll or its core from any latch other than by pushing or pulling on the roll or the core. In another embodiment, one of the stops is pivoted either to trap the core between the one stop and another stop or to enable the core to be slid onto the support to a position between the stops or to be slid off the support.

Abstract: There is disclosed an applicator and method for applying transfers such as heat transfers, decals or labels to transfer-receptive materials. The applicator has a lightweight, T-shaped, sheet metal support or frame having an applicator station. A motorized supply roll unwind and a motorized take-up roll rewind are mounted on the support to hold supply and take-up rolls, to tension the transfer-containing web and to advance the web onto the take-up roll after the transfer has been applied at the applicator station.

Abstract: There is disclosed an improved stacker, method of stacking sheets such as tags, and a stack of sheets. The stacker and the stacking method produces a stack of sheets, wherein same-size sheets are stacked so that the endmost sheet or sheets in one batch are offset or staggered to provide batch separators in a stack of sheets. The stacker includes an improved sheet feed mechanism that enables sheets having different characteristics to be fed without disassembling any portion of the mechanism or the stacker.

Abstract: There is disclosed a stacker used in conjunction with a cutter, wherein the stacker has a roller assembly which is pivotally mounted to facilitate in servicing and for clearing jams. The stacker is positioned close to a cutter assembly to enable short labels to be received and advanced by the stacker.

Abstract: There is disclosed thermal printer capable of printing on both sides of a web in a single pass wherein there is a straight-through path for the web for ease of threading of a printable web and for simplicity and economy of manufacture, maintenance and use. Print head assemblies can be quickly and easily located at the printing position and yet they can be moved to open or ineffective positions for threading, for cleaning the print head and for maintenance.

Abstract: Apparatus for cutting a continuously fed web into sheets and for vertically stacking such sheets. The apparatus receives the web between a pair of cutting knives, one of which is periodically rotatable by a motor periodically connected thereto by a pulse fed electrical clutch, and the resulting sheets are conveyed to a vertical stacker by a plurality of laterally spaced conveyor belts driven by the motor. The stacker has a pair of sheet receiving uprights adjustable toward and away from each other and which are mounted on an adjustable stop for engaging the leading edges of the sheets. The stop and the uprights are adjustable in angle with respect to the vertical. A roller below the stack has either crown portions beneath the belt or non-circular portions between pairs of belts to urge the sheets into the stack. Stripping fingers are between pairs of belts for removing the sheets from the belts. To prevent throwing of the sheets, a hold-down roller engages the web adjacent to where it is cut.
