Abstract
Abstract A device for packing a bunch of elongated objects, such as flowers, in a tight foil wrapping. The device having two foil strips feeding to a supporting member from two foil feed rollers. The supporting member receives the foil strips, permits joining of the ends, supports the bunch of objects and then opens, permitting the foil and bunch of objects to sink down. The supporting member then closes and foil rollers rotate in the opposite direction bringing the foil tightly around the bunch of objects, joins the strips together and cuts the wrapped bunch free from the strips.

Dependent Claim
16 words
A device as claimed in claim 1 wherein said power means is a pneumatic setting cylinder.
Claim 10
Dependent Claim
48 words
A device as claimed in claim 1 wherein a spring mechanism is coupled to said supporting means such that said spring mechanism tends to urge said supporting means in a direction such that one of said packing material unwinds from at least one of said packing material rollers.
Claim 11
Dependent Claim
65 words
A device as claimed in claim 1 wherein a wedge means is provided for spacing apart said first and second stop beams when said support members are near said second position, such that said packing material may be tightened about said elongated objects and after said packing material is tightened, said wedge means being withdrawable allowing said support members to close into said second position.
Claim 12
Dependent Claim
41 words
A device as claimed in claim 1 wherein said sealing and cutting means has a plurality of knife-like pointed members adapted to be heated electrically and to be displaced across said foil parallel to the longitudinal direction of said elongated objects.
Claim 13
Dependent Claim
25 words
A device as claimed in claim 11 wherein said knife-like or pointed members are fastened to a support element disposed in said first stop beam.
Claim 14
Dependent Claim
78 words
A device as claimed in claim 12 wherein said first stop beam is provided with a slot and said support element is provided With a guide which cooperates with said slot such that when said support element is longitudionally displaced, said knife-like members being contained within said first stop beam are forced to project from said first stop beam and travel longitudinally before being retracted into said first stop beam and thereby cut and seal said foil strips.
Claim 15
Dependent Claim
