ABSTRACT:
An apparatus for feeding and wrapping products comprising a wrapping machine, which machine has a driving element, and a device for feeding products to the wrapping machine. The feeding device includes a first conveyor for receiving products from a dispensing apparatus, which conveyor continuously moves at either a high or a low speed, and a second conveyor which connects the first conveyor to the wrapping machine and which continuously moves at one speed in the same direction as the first conveyor. A stop element is located at the end of the second conveyor adjacent the wrapping machine. There are provided first and second controls positioned along the second conveyor at selected spacings from the wrapping machine, with each control sensing the presence or absence of products on the second conveyor. A first drive is connected to the first conveyor and is adapted to operate the first conveyor at either the high or the low speed. A switch is connected to the first control and the driving element for the wrapping machine to deactivate the driving element for the wrapping machine when the first control senses the absence of products on the second conveyor. A second drive is connected to the second control and is adapted to operate the first drive in response to the sensed absence or presence by the second control of products on the second conveyor, wherein the second drive activates the first drive at the high speed if there is an absence of products at the second control, and the second drive activates the first drive at the low speed if there is a presence of products at the second control.
