<p>The press [20] for fusing heads [25] heats the tops of beads [25] to fuse the beads [25] together, fixing them in a pattern. The press [20] includes an enclosure [21] having a slot [32] defined in the front face [18]. A heating plate [120] having a heating element [130] is mounted within the enclosure [21]. A tray [22], which holds the beads [25] to be fused, is placed on a tray support [94] that slides within the open slot [32] to a position under the heating plate [120]. A control circuit [200] senses the position of the tray support [94], and when the tray [22] is in position beneath the heating plate [120], allows an operator to initiate a timed heating cycle and locks the tray [22] in place. When the heating cycle is initiated, the heating plate [120] is brought into close proximity with the tray [22], placing the tops of the beads [25] into contact with the heating plate [120] and energy the heating element [130] to heat the heating plate [120] to a predetermined temperature.</p> |
