Abstract: A semi-automatic linerless label dispenser effectively dispenses labels from a support for a supply of continuous form linerless labels, each label having a pressure sensitive adhesive face and an adhesive-release material face. First and second grooved drive rolls engage the labels and first and second sets of stripper and guiding fingers disposed in at least some of the grooves of the drive rolls guide the labels and prevent them from sticking to the drive rolls. At least the first drive roll and the first set of stripper fingers have adhesive-release material portions (e.g. plasma coatings) which engage the adhesive face of labels from the supply. An automatic cutter mounted on the opposite side of the stripper and guiding fingers from the support includes pivotally movable and stationary blades, and a silicone-impregnated felt wiper.

Abstract: A linerless label dispenser includes a cutting mechanism. Linerless labels are transported from a roll underneath a plastic guide and onto an adhesive-release material guide structure/ramp past a sensor to a print head which prints indicia on the release material coated face of the labels. From the print head and cooperating print roller the labels pass to a plasma coated stripper surface which is disposed at an upwardly directed angle between about 20-35.degree. with respect to the horizontal, and into contact with a plasma coated stationary anvil blade. The anvil blade is spaced downwardly from the stripper surface a distance of about 0.001-0.008 inches (preferably about 0.002-0.004 inches) and cooperates with a plasma coated or texture painted rotary blade of a rotary cutter. Downstream of the blades may be a plasma coated exit roller typically cooperating with a hold down mechanism for dispensing individual cut labels.

Abstract: A bevel angle indicator for a saw 10 consists of a table 16, a pivot support 26 pivotally mounted with respect to the table 16 about a bevel axis 92 and a mechanical saw blade pivotally mounted with respect to the pivot support 26 about a second axis 28. The pivot support 26 pivots on a pivot block 27 attached to the table 16. A gearing mechanism couples the pivot block 27 and the pivot support 26 to a dial which indicates the angle between the surface of the table 16 and the plane of the saw blade. The gearing mechanism comprises a rack 50 attached to the pivot block 27 and a pinion 54 rotatably journalled in the pivot support 26. Adjustment of the bevel angle of the saw 10 causes the pinion 54 to advance along the rack 50 and therefore rotate relative to the pivot support 26. The pinion 54 is attached to a sleeve 52, the free end of which carries a pointer 56; the pivot support 26 carries a scale 58. The pointer 56 and scale 58 indicate with accuracy the current bevel angle of the saw.
