Abstract
A system for end-folding a wrapping onto a stack of bags includes a folding machine having a first folding station and a second folding station. The first folding station configured to receive the stack of bags with the wrapping partially covering the stack of bags and defining wrapping flaps, and is further configured to end-fold one or more of the wrapping flaps of the wrapping onto the stack of bags while leaving other flaps unfolded. The second folding station is downstream from the first folding station is configured to receive the stack of bags from the first folding station and further end-fold unfolded wrapping flaps of the wrapping onto the stack of bags.
Claims7
A system for end-folding a wrapping onto a stack of bags, the system comprising:
- a folding machine that includes:
- a first bullnose and a second bullnose each configured to end-fold one or more wrapping flaps of the wrapping onto the stack of bags while leaving at least two wrapping flaps extending away from the stack of bags;
- a conveyor configured to receive the stack of bags thereon and longitudinally move the stack of bags downstream along an axis;
- a first folding plate configured to laterally move toward the axis and end-fold at least one of the wrapping flaps extending away from the stack of bags;
- and
- a second folding plate configured to laterally move toward the axis and end- fold the other wrapping flaps extending away from the stack of bags;
- and
- wherein the first bullnose and the second bullnose vertically move to thereby end fold the wrapping flaps.

- a first bullnose configured to end-fold one or more wrapping flaps of the wrapping onto the stack of bags while leaving at least two wrapping flaps extending away from the stack of bags;
- a conveyor configured to receive the stack of bags thereon and longitudinally move the stack of bags downstream along an axis;
- a first folding plate configured to laterally move toward the axis and end-fold at least one of the wrapping flaps extending away from the stack of bags;
- and
- a second folding plate configured to laterally move toward the axis and end- fold the other wrapping flaps extending away from the stack of bags;
- and
- wherein the conveyor is configured to longitudinally move the stack of bags downstream and subsequently longitudinally move the stack of bags upstream before again longitudinally moving the stack of bags downstream such that the first folding plate and the second folding plate end-fold the wrapping flaps.

- and
- wherein the second folding plate is located downstream from the first folding plate.
