Strap directing device
View Patent ↗A guide for guiding strap material from a dispenser to a strapper directs strap between the dispenser and strapper when in different positions in relation to each other. The guide includes an element having an open central passage defining a pathway for strap material to pass therethrough. The guide receives strap material in a first direction, and allows the strap material to exit in a second direction. The guide has bearing surfaces that define the passage so that when the strap material changes directions, there is minimal friction between the strap and the guide.
1. A guide for directing strap material from a dispenser to a strapper, the guide comprising:
a hollow element having an open central passage capable of allowing strap material to pass therethrough, the hollow element having an entry portion and an exit portion, the exit portion having internal exit portion bearing elements that define an inner periphery of the passage, wherein the guide is capable of allowing the strap material to enter the passage at the entry portion in one direction and exit the passage at the exit portion in a second direction wherein the entry portion has internal entry portion bearing elements and wherein the entry portion internal bearing elements are pin rollers mounted to the sidewalls.
2. The guide in accordance with claim 1 , wherein the hollow element is a rectangular tube comprising two pairs of opposing sidewalls.
3. The guide in accordance with claim 2 , wherein the exit portion bearing elements are disposed adjacent the sidewalls.
4. The guide in accordance with claim 3 , wherein the exit portion bearing elements are pin rollers mounted to the sidewalls.
5. The guide in accordance with claim 1 , wherein the exit portion bearing elements extend substantially about an entirety of an inner periphery of the hollow element at the exit portion.
6. A guide for directing strap material from a dispenser to a strapper, the guide comprising:
a hollow element having an open central passage capable of allowing strap material to pass therethrough, the hollow element having an entry portion and an exit portion, the exit portion having internal exit portion bearing elements that define an inner periphery of the passage, wherein the guide is capable of allowing the strap material to enter the passage at the entry portion in one direction and exit the passage at the exit portion in a second direction wherein the entry portion has internal entry portion bearing elements and wherein the entry portion bearing elements extend substantially about an entirety of an inner periphery of the hollow element at the entry portion.
7. A guide for directing strap material from a dispenser to a strapper, the guide comprising:
a hollow sleeve-like element having an open central passage for carrying strap material passing therethrough, the sleeve-like element having an entry and an exit, the exit having a exit bearing surface that defines an inner periphery of the passage, wherein strap material enters the passage at the entry and exits the passage at the exit, and wherein strap material is directed, as it exits the passage, by the exit bearing surface wherein the exit bearing surface is defined by a plurality of exit pin bearings mounted in an inner periphery of the element at about the exit.
8. The guide in accordance with claim 7 wherein the exit pin bearings extend substantially about an entirety of the inner periphery of the element.
9. The guide in accordance with claim 7 , wherein the entry includes an entry bearing surface in the inner periphery of the element at about the entry.
10. The guide in accordance with claim 9 , wherein the entry bearing surface is defined by a plurality of entry pin bearings mounted in the inner periphery of the element at about the entry.
11. The guide in accordance with claim 10 wherein the entry pin bearings extend substantially about an entirety of the inner periphery of the element at the entry.
