Abstract: An apparatus is disclosed for peeling logs to produce veneer sheet. The apparatus utilizes concentric spindles and dogs to grip the ends of the logs being peeled with the outer spindle and dog being retractable away from the ends of the logs after the outer portion of the log has been peeled. The innermost dog gripping each end of the log is smaller in diameter than the spindle on which it is mounted so that a greater percentage of the log can be peeled by the apparatus. The apparatus is particularly useful for increasing the percentage of veneer sheet obtained by peeling small logs, i.e., logs having a diameter of ten inches or less.

Abstract: A tray is formed from coated paperboard or plastic and is provided with a top peripheral flange onto which a tray lid is sealed.

Abstract: An elongated, plastic resealing clip is provided for a bag containing a flowable product and comprising a plurality of panels hingedly coupled along fold lines, an opening at one end of the bag, and a flap hingedly coupled to one panel along a fold line for overlapping an opposite panel and closing the opening. The clip is U-shaped in transverse cross section with a bight for engaging the flap fold line and depending legs for pressing the flap against the opposite panel. An adhesive layer extends across the entire width of the flap to seal the flap to the opposite panel. The adhesive layer seal can have a reduced bonding strength adjacent one end of the flap to facilitate opening of the flap at the reduced bond strength section. The reduced bonding strength is provided by an adhesive coating comprising kaolin clay. This arrangement is particularly useful in heavy weight bags which are sealed by a hot melt adhesive.

Abstract: A remote controlled slack pulling log skidding carriage is provided for feeding a slack drag line toward a log to be skidded. A drive sheave rotatably mounted in the carriage is operated by a hydraulic motor. The fluid to operate the motor is stored in one or more accumulators, and a radio controlled valve starts and stops the flow of fluid to the motor. A mechanically operated hydraulic pump also is provided to recharge the accumulators during a skidding operation. A reciprocating locking assembly is provided to alternately lock the carriage to the skyline or to the slack line.

Abstract: A mechanism for stacking and weighing sheets fed from a semi-continuous sheet cutter. The mechanism includes a hydraulic cylinder operatively connected to a stacking table so that as sheets are deposited onto the stacking table, the table is lowered by indexing the hydraulic cylinder. This continues until a full stack of sheets, having a predetermined number of sheets determined by weight, by height of the stack or by sheet count has been stacked on the table. The hydraulic cylinder comprises a hydraulic fluid reservoir, an electrically driven hydraulic pump, a four-way, three position hydraulic spool valve, a hydraulic cylinder and back pressure safety valve. A load cell connected between the hydraulic cylinder and the rest of the mechanism is connected to a scale device which will weigh the stack of sheets.

Abstract: This invention provides a process for the lamination of a polyester, particularly polyethylene terephthalate, to a paperboard substrate which comprises coextruding a polyester layer and a polymeric adhesive layer onto a paperboard substrate. By use of this process, well adhered coatings of polyester can be obtained where the polyester is used in amounts as low as 10 pounds of polyester per ream. The adhesive layer can be pigmented thereby providing visual enhancement of the laminate product. Moreover, the paperboard can be treated with sizing agents or the like without serious adverse effects on the adherence of the polyester layer. Laminates produced in accordance with this invention are less costly than those of the prior art as they include less polyester per unit of surface.
