    摘要: Apparatus and process for trimming articles molded on a plastic sheet and successively fed from a forming machine. A carriage (10) receives the article ( b ) to be suckingly held thereunder and is moved in a trimming zone (II), where a pair of longitudinal cutter devices (20, 20′), each having a stationary blade (22′) and an angularly movable blade (24′) are horizontally moved together from respective retreated positions for longitudinal cutting. Then, a front transverse cutter device (30) having similar pair of blades is raised up from retreated position for transverse cutting and then a rear transverse cutter device (30′) is similarly operated.

    摘要: A device for centering plastic webs automatically fed thereon one by one so as to feed it to a pair of cramp chains to be correctly gripped thereby at the opposite side edges. This comprises a bed (10) consisting of a central frame (11) and longitidinal as well as transverse arms (12a, 12b; 13a, 13b) respectively extended in opposite directions from the central frame for supporting the web of varied size. A plurality of pairs of centering members (21a, 21b; 22a, 22b; 23a, 23b), each having an upwardly projected pin (24), are oppositely arranged and adapted to move toward and apart with each other so as to abut on the longitudinal and transverse side edges of web on the table with said pin for centering. It is preferable and sufficient to move said centering members by means of a belt and pulleys for treating a light web.

    摘要: Plastic web to be fed into opposite dies for forming articles must be heated and softened by heater means in front of the forming machine, even if said machine is combined with an extruder supplying said plastic web. The invention provides a radiant heater adapted to be sensitively responsive to manual or automatic control so as to more suitably regulate a temperature of the plastic web in comparison with the conventional heater comprising quartz tubes each having a coiled nichrome wire. The heater of the invention comprises an extended thin nichrome electrical resistance heater element plate (30) arranged in a zig-zag on a support plate (11) and insulating plate (13).
