    • A packaging machine of the type that is used to hand-wrap a package with a stretchable film that is heat-fused/seaied. The machine includes a supply of film for wrapping a package and a hot plate mechanism for heat fusing the film after the package is wrapped. The hot piate mechanism includes a fever arm that moves a sealing platform from a raised position to a lowered, heat sealing position when the package is piaced on the platform. A control circuit energizes a heating element forming part of the seaiing platform and causes it to reach a desired heating temperature in 2 to 4 seconds, whereby fusing of the sealing film is achieved. An interval timer is used to control a signaling device such as a light to Indicate the machine is in a heating cycle. A separate timer, in conjunction with a temperature sensing thermistor, controls a length of time the heating element is energized and terminates power to the heating element prior to the end of a sealing Interval if a predetermined temperature is exceeded. The sealing intervals are selectable by the operator using a muiti- posϊtioned switch which connects selected timing resistors to the interval timers. Power to the heating element is only delivered to the heating element during a heating cycle, thus conserving electrical power,
    • 一种包装机,用于手工包装具有热熔/海洋的可拉伸薄膜的包装。 该机器包括用于包装的薄膜和用于在包装被包装之后使薄膜热熔融的热板机构。 热片机构包括发热臂,当包装被引导在平台上时,发热臂将密封平台从升高位置移动到降低的热封位置。 控制电路为形成扫描平台的一部分的加热元件通电,并使其在2至4秒内达到所需的加热温度,从而实现密封膜的熔合。 间隔定时器用于控制诸如光的信号装置,以指示机器处于加热循环。 单独的定时器与温度感测热敏电阻一起控制加热元件被激励的时间长度,并且在密封结束之前终止加热元件的功率如果超过预定温度则间隔。 密封间隔可由操作员使用一个连接选择的定时电阻器与间隔定时器连接的开关来选择。 加热元件的功率仅在加热循环期间传递到加热元件,从而节省电力,
