Abstract
1,229,838. Toothpicks. R. BARMAN. 12 June, 1968 [19 June, 1967], No. 27856/68. Heading A5R. Toothpicks of essentially triangular crosssection and tapered at both ends are produced by a) forming spaced, parallel, V-shaped grooves of uniform depth in a raw material, e.g. wood or plastic, by means of a relative movement between a first cutting means and the material and b) separating the toothpicks from the raw material by applying, at or adjacent the bottom of the grooves, a second cuting means forming separating faces on the toothpicks, each toothpick being formed, in step a), with an apex edge which is flat or of outwardly curved contour and, in step b), with a separating face which is flat or of outwardly curved contour, at least one of the apex edge and separating face being of outwardly curved contour. In the embodiment shown in Fig. 7, material 30 is led in the direction of arrow 31 past cutting teeth 33 on tool 32 which moves as shown by arrows 34 at the same time as it rotates as shown by arrow 35. Band knife 39 divides the cut rows of material into individual toothpicks 41.
