Abstract
Description
Claims (26)
- Apparatus (10) for making a bag of gas for protective packing, the apparatus comprising a source of compressed gas, a compressed gas supply pipe (32) and two rollers (18) arranged side by side and between which material (14) for making a bag passes, one or both of the rollers including a circumferential recess (34) and the recess (34) or both recesses (34) together receiving the supply pipe (32).
- Apparatus as claimed in claim 1, wherein the supply pipe (32) substantially fills the recess (34) or both recesses (34).
- Apparatus as claimed in claim 1 or 2, wherein the bag material (14) is provided as a strip.
- Apparatus as claimed in any of claims 1 to 3, wherein bag sealing means (22) is provided immediately downstream of the rollers (18).
- Apparatus as claimed in claim 4, wherein the sealing means (22) comprises heating sealing means.
- Apparatus as claimed in claim 1, wherein the gas source is a source of compressed air.
- Apparatus as claimed in claim 4 or 5 in which clamping means (42) is provided for clamping the bag downstream of the sealing means.
- Apparatus as claimed in claim 7, wherein the clamping means (42) comprises a resilient member (42) which is urged against the bag.
- Apparatus as claimed in claim 8, wherein the clamping means (42) comprises two resilient clamping members (42) arranged on opposite sides to clamp a bag between them.
- Apparatus as claimed in any of claims 7 to 9, wherein the clamping means (42) is arranged to clamp the bag before the sealing means starts to seal the bag.
- Apparatus as claimed in any of claims 7 to 9, wherein a clamping member (42) of the clamping means and a sealing member (22) of the sealing means are mounted together on a mounting member.
- Apparatus as claimed in claim 11, wherein on the mounting member, the clamping member (42) is resiliently mounted ahead of the sealing member (22) so as to engage the bag before the sealing member.
- Apparatus as claimed in claim 11 or 12, wherein a second mounting member is provided which mounts one of a second clamping member (42) and a second sealing member (22).
- Apparatus as claimed in claim 13, wherein only one of the first and second mounting members is movable.
- Apparatus as claimed in claim 13, wherein both of the first and second mounting members are movable towards and away from each other.
- Apparatus as claimed in any of claims 11 to 15, wherein the or each mounting member is moved pneumatically.
- Apparatus as claimed in any preceding claim, wherein the apparatus is arranged to operate in a cycle.
- Apparatus as claimed in any preceding claim, wherein the bag material (14) is in the form of two layers open at one side, the gas supply pipe (32) extending between the layers through the open side.
- Apparatus as claimed in claim 18, wherein the material (14) is open on only one side.
- Apparatus as claimed in claim 18 or 19, wherein means is provided for sealing the open side.
- Apparatus as claimed in claim 20, wherein the open side of the material is sealed by side sealing means (28) upstream of the end of the supply pipe.
- Apparatus as claimed in claim 21, wherein the side sealing means (18) comprises heat sealing means (28).
- Apparatus as claimed in claim 21 or claim 22, wherein the side sealing means (28) comprises a member which is movable towards and away from the side of the material.
- Apparatus as claimed in any of claims 20 to 23 wherein side sealing means (28) is provided for sealing the open side of the material upstream of the end of the supply pipe (32), and wherein the bag sealing means (22) and the side sealing means (28) are rigidly connected and movable together.
- Apparatus as claimed in claim 24, wherein the bag sealing means (22) and the side sealing means (28) are movable by pneumatic means.
- Apparatus as claimed in any preceding claim, wherein the apparatus includes means for advancing material for making a bag from a store.
