The fold actuators 132a and 132b reset the napkin folders 131a and 131b, when the napkin 501 folded around the utensils 502 is conveyed to the release end 105b of the set of conveyor belts 105.

[0033] The napkin 501 with the folded leading corner 501b and the folded opposing corners 501c and 501d is then conveyed to the rolling station 112 of the utensil wrapping apparatus 100. The folded napkin 501 with the utensils 502 traverses along the set of conveyor belts 105 and enters the roll starter and tuck assembly 117 of the rolling station 112. The drive roller 124, running in conjunction with the set of conveyor belts 105, powers up the rolling station 112 and the second set of rolling belts 127 that roll on the roller shafts 118, 119, and 120 respectively. The roll starters 136 of the roll starter and tuck assembly 117 initiate the rolling of the folded napkin 501, and the tuckers 137 of the roll starter and tuck assembly 117 tuck the top layer 501a of the folded napkin 501 adjacent to one end of the utensils 502 inward during rolling to close one end of the bundle thus formed as exemplarily illustrated in FIG. 5D. The roll starter and tuck assembly 117 resets after the rolling of the folded napkin 501 around the utensils 502.

[0034] The folding and rolling functions of the utensil wrapping apparatus 100 wrap the napkin 501 around the utensils 502. The set of rolling belts 127 of the rolling station 112 move in a direction counter to the movement of the set of conveyor belts 105 as exemplarily illustrated in FIG. 5D, thereby accelerating the rolling speed of the napkin 501 rolled around the utensils 502. The set of rolling belts 127 convey the rolled and tucked napkin 501 around the utensils 502 over the set of conveyor belts 105. The rolled and tucked napkin 501 around the utensils 502 glides over the set of conveyor belts 105 to the release end 105b of the set of conveyor belts 105 and is delivered out of the utensil wrapping apparatus 100 to the operator for placement on a dining table in the restaurant. In an embodiment, the operator uses the control panel 129 to stop the first set of belt rollers 104, and in turn the set of conveyor belts 105, and to stop the second set of belt rollers 121, 122, and 123, and in turn the set of rolling belts 127. The utensil wrapping apparatus 100 is then ready for the next cycle of wrapping the next napkin 501 around another set of utensils 502.
