PURPOSE:To hold the high quality of a completed product by changing over the injection of paste to spot like injection and linear injection corresponding to the moving speed of a packing piece and detecting the number of spots and an injection position at the time of spot-like paste and detecting the length of the paste and the injection position thereof at the time of using linear paste. CONSTITUTION:A packing piece detector 5 detecting the presence of a pcking piece 1a is provided on the upstream side of a paste gun 2 and a paste detector 6 for detecting the presence of paste B is provided on the downstream side thereof. Both detectors 5, 6 and the paste gun 2 are electrically connected by a change-over means 7 and it is judged whether the packing piece 1a is within a variable speed moving region or a constant speed moving region corresponding to the moving speed of the packing piece 1a and, when the packing piece 1a is within the variable speed moving region, the paste gun 2 is intermittently operated for a set time to output only the differentiation rising signal from the paste detector 6 and, when the packing paste is within the constant speed moving region, the paste gun 2 is continuously operated for a set time to output the differentiation rising and falling signals from the paste detector 6. As a result, a completed product can be held the high quality.
