Abstract
Abstract A method of and a device for packaging blocks of foamed synthetic material in which a pair of parallel plates are mounted on a frame and are movable toward and away from each other for compressing blocks of resilient material therebetween. The machine may include blocking members for holding the articles in compressed condition and is adapted for receiving a package in which the articles can be compressed and which is provided with a releasable closure element at one end.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
67 words
The method of packaging block like articles of foamed elastic material to reduce transporting costs thereof which comprises in combination the steps of: arranging the articles in face to face engagement and in alignment, compressing the articles individually in the direction of alignment thereof to assure stable characteristics thereof, stacking the individually compressed articles in compressed condition, and finally enclosing the individually compressed articles in a package.
Claim 2
Independent Claim
67 words
The method of packaging block like articles of foamed elastic material to reduce transporting costs thereof which comprises in combination the steps of: arranging the articles in face to face engagement and in alignment, compressing the articles individually in the direction of alignment thereof to assure stable characteristics thereof, stacking the individually compressed articles in compressed condition, and finally enclosing the individually compressed articles in a package.
Claim 3
Dependent Claim
38 words
The method in combination according to claim 1 in which each article is compressed individually by about 70 to 90 per cent of the normal dimension of the article in the said direction of alignment of the article.
Claim 4
Dependent Claim
35 words
The method in combination according to claim 1 in which the articles are formed by foaming a material in a principal direction, said compressing of each article individually taking place in the same principal direction.
Claim 5
Independent Claim
128 words
An apparatus for the compression of resilient foamed articles to reduce transporting costs thereof and comprising in combination; a press frame, a pair of press plates upstanding from the press frame in spaced parallel relation for receiving the articles individually to be compressed therebetween to assure stable characteristics thereof, means for moving said press plates toward and away from each other, blocking elements on said press frame displaceable thereon in the pressing direction of relative movement of said press plates and guided on said press frame, means for arresting said blocking elements in adjusted positions along said press frame, and means supporting said blocking elements on said press frame for movement thereof on the press frame transverse to the pressing direction into space provided between said press plates.
Claim 6
Independent Claim
128 words
An apparatus for the compression of resilient foamed articles to reduce transporting costs thereof and comprising in combination; a press frame, a pair of press plates upstanding from the press frame in spaced parallel relation for receiving the articles individually to be compressed therebetween to assure stable characteristics thereof, means for moving said press plates toward and away from each other, blocking elements on said press frame displaceable thereon in the pressing direction of relative movement of said press plates and guided on said press frame, means for arresting said blocking elements in adjusted positions along said press frame, and means supporting said blocking elements on said press frame for movement thereof on the press frame transverse to the pressing direction into space provided between said press plates.
Claim 7
Dependent Claim
29 words
An apparatus in combination according to claim 4 which includes stationary guiding bars parallel to the direction of relative movement of said plates and slidably supporting said blocking elements.
Claim 8
Dependent Claim
39 words
An apparatus in combination according to claim 4 in which said blocking elements comprise spaced finger-like elements extending in the transverse direction and adapted to enter a package in which the articles are being individually compressed from the sides
Claim 9
Dependent Claim
50 words
An apparatus in combination according to claim 4 which includes at least one guiding bar on the side of the press frame parallel to the direction of relative movement of said plates along which said blocking elements are slidable and about the axis of which said blocking elements are tiltable.
Claim 10
Dependent Claim
54 words
An apparatus in combination according to claim 4 which includes means for supporting a package on said frame which is open at at least one end for receiving articles to be compressed individually and a pressing plate and having longitudinal slots on the sides for receiving blocking elements in the form of transverse fingers.
Claim 11
Dependent Claim
26 words
An apparatus in combination according to claim 8 in which said package includes a closure element adapted to latch on said one end of said package.
Claim 12
Dependent Claim
45 words
An apparatus in combination according to claim 9 which includes means for braking the opening movement of the closure element slowed down when the latch is released and the articles compressed in the package commence to expand through the said one end of the package.
