Abstract: The invention provides coating compositions having improved scratch and mar resistance. The curable coating compositions of the invention comprise a film-forming component (A) comprising one or more active hydrogen containing components (a), and one or more curing agents (b) comprising at least one aminoplast resin (bi) having from 0.5 to 3.5 moles of NH per mole of aminoplast resin (bi), a blocked acid catalyst (B) having a blocking agent which is not a tertiary amine, and a tertiary amine (C) present in an amount equal to 10 to 150% by weight of the blocking agent. The invention farther provides a method of making cured coated substrates having improved scratch and mar resistance as well as a method of making multilayer coating compositions.

Abstract: There is disclosed a method and apparatus for making a looped label and accumulating labels in a stack. An intermediate portion of the label is inserted into the nip of a pair of rotating rolls which fold or loop the label into two side-by-side or face-to-face label portions. The looped label is transported between the nip of a pair of pressing rolls which press or iron the label at the fold line while the label is stationary between the rolls to maintain the label in the folded condition. From there the label is passed into a stacker in which successively looped labels are stacked.

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: An assembly is provided including two members capable of relative rotation about a common axis, and with electrical interconnections extending between the two members, the assembly, being for example, part of a gimbal system, wherein the electrical interconnections may be divided into two groups, selected such that, because of the voltages, and/or currents, carried by the electrical interconnections, it is desired that the electrical interconnections of one group are screened electrically from the electrical interconnections of the other group, by a screen which does not extend along the whole length of either group.

Abstract: A die, preferably one with internal metering pumps for applying an extremely uniform coating to a traveling web, is mounted over a pair of very rigid side plates. Horizontal surfaces of the plates support linear slides which in turn support the die through uprights. The slides have preloaded bearings to allow a linear movement of each upright with no lost motion. Pneumatic cylinders move each upright along its slide independently of the other upright. Adjustable stops set the die-to-web spacing when the cylinders draw the uprights, and therefore the die, toward the web. Other air/hydraulic cylinders drive the uprights away from the web, against the action of the main cylinders, to jump splices in the web. The system preferably includes an outrigger arm extending from each upright to a pair of auxiliary linear slides mounted on the side face of each side plate to relieve side loading on the main linear slides.
